      nvme: fix memory leak caused by incorrect subsystem free · e654dfd3
      Logan Gunthorpe authored
      When freeing the subsystem after finding another match with
      __nvme_find_get_subsystem(), use put_device() instead of
      __nvme_release_subsystem() which calls kfree() directly.
      
      Per the documentation, put_device() should always be used
      after device_initialization() is called. Otherwise, leaks
      like the one below which was detected by kmemleak may occur.
      
      Once the call of __nvme_release_subsystem() is removed it no
      longer makes sense to keep the helper, so fold it back
      into nvme_release_subsystem().

      io_uring: track io length in async_list based on bytes · 9310a7ba
      Zhengyuan Liu authored
      We are using PAGE_SIZE as the unit to determine if the total len in
      async_list has exceeded max_pages, it's not fair for smaller io sizes.
      For example, if we are doing 1k-size io streams, we will never exceed
      max_pages since len >>= PAGE_SHIFT always gets zero. So use original
      bytes to make it more accurate.

      io_uring: don't use iov_iter_advance() for fixed buffers · bd11b3a3
      Jens Axboe authored
      Hrvoje reports that when a large fixed buffer is registered and IO is
      being done to the latter pages of said buffer, the IO submission time
      is much worse:
      
      reading to the start of the buffer: 11238 ns
      reading to the end of the buffer:   1039879 ns
      
      In fact, it's worse by two orders of magnitude. The reason for that is
      how io_uring figures out how to setup the iov_iter. We point the iter
      at the first bvec, and then use iov_iter_advance() to fast-forward to
      the offset within that buffer we need.
      
      However, that is abysmally slow, as it entails iterating the bvecs
      that we setup as part of buffer registration. There's really no need
      to use this generic helper, as we know it's a BVEC type iterator, and
      we also know that each bvec is PAGE_SIZE in size, apart from possibly
      the first and last. Hence we can just use a shift on the offset to
      find the right index, and then adjust the iov_iter appropriately.
      After this fix, the timings are:
      
      reading to the start of the buffer: 10135 ns
      reading to the end of the buffer:   1377 ns
      
      Or about an 755x improvement for the tail page.

      block: properly handle IOCB_NOWAIT for async O_DIRECT IO · 6a43074e
      Jens Axboe authored
      A caller is supposed to pass in REQ_NOWAIT if we can't block for any
      given operation, but O_DIRECT for block devices just ignore this. Hence
      we'll block for various resource shortages on the block layer side,
      like having to wait for requests.
      
      Use the new REQ_NOWAIT_INLINE to ask for this error to be returned
      inline, so we can handle it appropriately and return -EAGAIN to the
      caller.

      io_uring: add a memory barrier before atomic_read · c0e48f9d
      Zhengyuan Liu authored
      There is a hang issue while using fio to do some basic test. The issue
      can be easily reproduced using the below script:
      
              while true
              do
                      fio  --ioengine=io_uring  -rw=write -bs=4k -numjobs=1 \
                           -size=1G -iodepth=64 -name=uring   --filename=/dev/zero
              done
      
      After several minutes (or more), fio would block at
      io_uring_enter->io_cqring_wait in order to waiting for previously
      committed sqes to be completed and can't return to user anymore until
      we send a SIGTERM to fio. After receiving SIGTERM, fio hangs at
      io_ring_ctx_wait_and_kill with a backtrace like this:

      The reason is that we had added a req to ctx->pending_async at the very

                list_add_tail()
                atomic_read() << 0 or 1?
      
      As atomic_ops.rst states, atomic_read does not guarantee that the
      runtime modification by any other thread is visible yet, so we must take
      care of that with a proper implicit or explicit memory barrier.

      rq-qos: fix missed wake-ups in rq_qos_throttle · 545fbd07
      Josef Bacik authored
      We saw a hang in production with WBT where there was only one waiter in
      the throttle path and no outstanding IO.  This is because of the
      has_sleepers optimization that is used to make sure we don't steal an
      inflight counter for new submitters when there are people already on the
      list.
      
      We can race with our check to see if the waitqueue has any waiters (this
      is done locklessly) and the time we actually add ourselves to the
      waitqueue.  If this happens we'll go to sleep and never be woken up
      because nobody is doing IO to wake us up.
      
      Fix this by checking if the waitqueue has a single sleeper on the list
      after we add ourselves, that way we have an uptodate view of the list.

      wait: add wq_has_single_sleeper helper · a6d81d30
      Josef Bacik authored
      rq-qos sits in the io path so we want to take locks as sparingly as
      possible.  To accomplish this we try not to take the waitqueue head lock
      unless we are sure we need to go to sleep, and we have an optimization
      to make sure that we don't starve out existing waiters.  Since we check
      if there are existing waiters locklessly we need to be able to update
      our view of the waitqueue list after we've added ourselves to the
      waitqueue.  Accomplish this by adding this helper to see if there is
      more than just ourselves on the list.

      block, bfq: check also in-flight I/O in dispatch plugging · b5e02b48
      Paolo Valente authored
      Consider a sync bfq_queue Q that remains empty while in service, and
      suppose that, when this happens, there is a fair amount of already
      in-flight I/O not belonging to Q. In such a situation, I/O dispatching
      may need to be plugged (until new I/O arrives for Q), for the
      following reason.
      
      The drive may decide to serve in-flight non-Q's I/O requests before
      Q's ones, thereby delaying the arrival of new I/O requests for Q
      (recall that Q is sync). If I/O-dispatching is not plugged, then,
      while Q remains empty, a basically uncontrolled amount of I/O from
      other queues may be dispatched too, possibly causing the service of
      Q's I/O to be delayed even longer in the drive. This problem gets more
      and more serious as the speed and the queue depth of the drive grow,
      because, as these two quantities grow, the probability to find no
      queue busy but many requests in flight grows too.
      
      If Q has the same weight and priority as the other queues, then the
      above delay is unlikely to cause any issue, because all queues tend to
      undergo the same treatment. So, since not plugging I/O dispatching is
      convenient for throughput, it is better not to plug. Things change in
      case Q has a higher weight or priority than some other queue, because
      Q's service guarantees may simply be violated. For this reason,
      commit 1de0c4cd ("block, bfq: reduce idling only in symmetric
      scenarios") does plug I/O in such an asymmetric scenario. Plugging
      minimizes the delay induced by already in-flight I/O, and enables Q to
      recover the bandwidth it may lose because of this delay.
      
      Yet the above commit does not cover the case of weight-raised queues,
      for efficiency concerns. For weight-raised queues, I/O-dispatch
      plugging is activated simply if not all bfq_queues are
      weight-raised. But this check does not handle the case of in-flight
      requests, because a bfq_queue may become non busy *before* all its
      in-flight requests are completed.
      
      This commit performs I/O-dispatch plugging for weight-raised queues if
      there are some in-flight requests.
      
      As a practical example of the resulting recover of control, under
      write load on a Samsung SSD 970 PRO, gnome-terminal starts in 1.5
      seconds after this fix, against 15 seconds before the fix (as a
      reference, gnome-terminal takes about 35 seconds to start with any of
      the other I/O schedulers).

      blkcg: allow blkcg_policy->pd_stat() to print non-debug info too · 07b0fdec
      Tejun Heo authored
      Currently, ->pd_stat() is called only when moduleparam
      blkcg_debug_stats is set which prevents it from printing non-debug
      policy-specific statistics.  Let's move debug testing down so that
      ->pd_stat() can print non-debug stat too.  This patch doesn't cause
      any visible behavior change.

      io_uring: fix counter inc/dec mismatch in async_list · f7b76ac9
      Zhengyuan Liu authored
      We could queue a work for each req in defer and link list without
      increasing async_list->cnt, so we shouldn't decrease it while exiting
      from workqueue as well if we didn't process the req in async list.
      
      Thanks to Jens Axboe <axboe@kernel.dk> for his guidance.

      sq->cached_sq_head and cq->cached_cq_tail are both unsigned int. If
      cached_sq_head overflows before cached_cq_tail, then we may miss a

       "Improvements and bug fixes for the hmm interface in the kernel:
      
         - Improve clarity, locking and APIs related to the 'hmm mirror'
           feature merged last cycle. In linux-next we now see AMDGPU and
           nouveau to be using this API.
      
         - Remove old or transitional hmm APIs. These are hold overs from the
           past with no users, or APIs that existed only to manage cross tree
           conflicts. There are still a few more of these cleanups that didn't
           make the merge window cut off.
      
         - Improve some core mm APIs:
             - export alloc_pages_vma() for driver use
             - refactor into devm_request_free_mem_region() to manage
               DEVICE_PRIVATE resource reservations
             - refactor duplicative driver code into the core dev_pagemap
               struct
      
         - Remove hmm wrappers of improved core mm APIs, instead have drivers
           use the simplified API directly

      Pull stream_open() updates from Kirill Smelkov:
       "This time on stream_open front it is only two small changes:
      
         - the first one converts stream_open.cocci to treat all functions
           that start with wait_.* as blocking. Previously it was only
           wait_event_.* functions that were considered as blocking, but this
           was falsely reporting several deadlock cases as only warning.
      
           This was picked by linux-kbuild and entered mainline as commit
           0c4ab18f ("coccinelle: api/stream_open: treat all wait_.*()
           calls as blocking"), and already merged earlier.
      
         - the second one teaches stream_open.cocci to consider files as being
           stream-like even if they use noop_llseek. It results in two more
           drivers being converted to stream_open() (mousedev.c and
           hid-sensor-custom.c)"

      Pull x86 platform driver updates from Andy Shevchenko:
       "Gathered a bunch of x86 platform driver changes. It's rather big,
        since includes two big refactors and completely new driver:
      
         - ASUS WMI driver got a big refactoring in order to support the TUF
           Gaming laptops. Besides that, the regression with backlight being
           permanently off on various EeePC laptops has been fixed.
      
         - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
           X axis being inverted. This has been fixed.
      
         - Intel PMC core driver has been extended to be ACPI enumerated if
           the DSDT provides device with _HID "INT33A1". This allows to
           convert the driver to be pure platform and support new hardware
           purely based on ACPI DSDT.
      
         - From now on the Intel Speed Select Technology is supported thru a
           corresponding driver. This driver provides an access to the
           features of the ISST, such as Performance Profile, Core Power, Base
           frequency and Turbo Frequency.
      
         - Mellanox platform drivers has been refactored and now extended to
           support more systems, including new coming ones.
      
         - The OLPC XO-1.75 platform is now supported.
      
         - CB4063 Beckhoff Automation board is using PMC clocks, provided via
           pmc_atom driver, for ethernet controllers in a way that they can't
           be managed by the clock driver. The quirk has been extended to
           cover this case.
      
         - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
           the information of Chuwi Hi10 Air has been fixed to cover more
           models based on the same platform.
      
         - Xiaomi notebooks have WMI interface enabled. Thus, the driver to
           support it has been provided. It required some extension of the
           generic WMI library, which allows to propagate opaque context to
           the ->probe() of the individual drivers.
      
        This release includes debugfs clean up from Greg KH for several
        drivers that drop return code check and make debugfs absence or
        failure non-fatal.
      
        Also miscellaneous fixes here and there, mostly for Acer WMI and

      Pull percpu updates from Dennis Zhou:
       "This includes changes to let percpu_ref release the backing percpu
        memory earlier after it has been switched to atomic in cases where the
        percpu ref is not revived.
      
        This will help recycle percpu memory earlier in cases where the
        refcounts are pinned for prolonged periods of time"
