Currently, struct request has four timestamp fields: - A start time, set at get_request time, in jiffies, used for iostats - An I/O start time, set at start_request time, in ktime nanoseconds, used for blk-stats (i.e., wbt, kyber, hybrid polling) - Another start time and another I/O start time, used for cfq and bfq These can all be consolidated into one start time and one I/O start time, both in ktime nanoseconds, shaving off up to 16 bytes from struct request depending on the kernel config.

cfq and bfq have some internal fields that use sched_clock() which can trivially use ktime_get_ns() instead. Their timestamp fields in struct request can also use ktime_get_ns(), which resolves the 8 year old comment added by commit 28f4197e ("block: disable preemption before using sched_clock()").

struct blk_issue_stat squashes three things into one u64: - The time the driver started working on a request - The original size of the request (for the io.low controller) - Flags for writeback throttling It turns out that on x86_64, we have a 4 byte hole in struct request which we can fill with the non-timestamp fields from blk_issue_stat, simplifying things quite a bit.

struct blk_issue_stat is going away, and bio->bi_issue_stat doesn't even use the blk-stats interface, so we can provide a separate implementation specific for bios.

issue_stat is going to go away, so first make writeback throttling take the containing request, update the internal wbt helpers accordingly, and change rwb->sync_cookie to be the request pointer instead of the issue_stat pointer.

Commit 9c40cef2 ("sched: Move blk_schedule_flush_plug() out of __schedule()") moved the blk_schedule_flush_plug() call out of the interrupt/preempt disabled region in the scheduler. This allows to replace local_irq_save/restore(flags) by local_irq_disable/enable() in blk_flush_plug_list(). But it makes more sense to disable interrupts explicitly when the request queue is locked end reenable them when the request to is unlocked. This shortens the interrupt disabled section which is important when the plug list contains requests for more than one queue. The comment which claims that disabling interrupts around the loop is misleading as the called functions can reenable interrupts unconditionally anyway and obfuscates the scope badly: local_irq_save(flags); spin_lock(q->queue_lock); ... queue_unplugged(q...); scsi_request_fn(); spin_unlock_irq(q->queue_lock); -------------------^^^ ???? spin_lock_irq(q->queue_lock); spin_unlock(q->queue_lock); local_irq_restore(flags); Aside of that the detached interrupt disabling is a constant pain for PREEMPT_RT as it requires patching and special casing when RT is enabled while with the spin_*_irq() variants this happens automatically.

Commit 2fff8a92 ("block: Check locking assumptions at runtime") added a lockdep_assert_held(q->queue_lock) which makes the WARN_ON() redundant because lockdep will detect and warn about context violations. The unconditional WARN_ON() does not provide real additional value, so it can be removed.

bounce_copy_vec() disables interrupts around kmap_atomic(). This is a leftover from the old kmap_atomic() implementation which relied on fixed mapping slots, so the caller had to make sure that the same slot could not be reused from an interrupting context. kmap_atomic() was changed to dynamic slots long ago and commit 1ec9c5dd ("include/linux/highmem.h: remove the second argument of k[un]map_atomic()") removed the slot assignements, but the callers were not checked for now redundant interrupt disabling.

Since the commit "8003c9ae: add APIC Timer periodic/oneshot mode VMX preemption timer support", a Windows 10 guest has some erratic timer spikes. Here the results on a 150000 times 1ms timer without any load: Before 8003c9ae | After 8003c9ae Max 1834us | 86000us Mean 1100us | 1021us Deviation 59us | 149us Here the results on a 150000 times 1ms timer with a cpu-z stress test: Before 8003c9ae | After 8003c9ae Max 32000us | 140000us Mean 1006us | 1997us Deviation 140us | 11095us The root cause of the problem is starting hrtimer with an expiry time already in the past can take more than 20 milliseconds to trigger the timer function. It can be solved by forward such past timers immediately, rather than submitting them to hrtimer_start(). In case the timer is periodic, update the target expiration and call hrtimer_start with it. v2: Check if the tsc deadline is already expired. Thank you Mika. v3: Execute the past timers immediately rather than submitting them to hrtimer_start(). v4: Rearm the periodic timer with advance_periodic_target_expiration() a simpler version of set_target_expiration().

Pull rdma fixes from Doug Ledford: "This is our first pull request of the rc cycle. It's not that it's been overly quiet, we were just waiting on a few things before sending this off. For instance, the 6 patch series from Intel for the hfi1 driver had actually been pulled in on Tuesday for a Wednesday pull request, only to have Jason notice something I missed, so we held off for some testing, and then on Thursday had to respin the series because the very first patch needed a minor fix (unnecessary cast is all). There is a sizable hns patch series in here, as well as a reasonably largish hfi1 patch series, then all of the lines of uapi updates are just the change to the new official Linux-OpenIB SPDX tag (a bunch of our files had what amounts to a BSD-2-Clause + MIT Warranty statement as their license as a result of the initial code submission years ago, and the SPDX folks decided it was unique enough to warrant a unique tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4 and core/cache/cma updates to round out the bunch. None of it was overly large by itself, but in the 2 1/2 weeks we've been collecting patches, it has added up :-/. As best I can tell, it's been through 0day (I got a notice about my last for-next push, but not for my for-rc push, but Jason seems to think that failure messages are prioritized and success messages not so much). It's also been through linux-next.

I managed to send some modpost patches to old addresses of both Masahiro and Michal, and omitted linux-kbuild from cc, because my tried and trusted scripts/get_maintainer wrapper failed me. Add the modpost directory to the MAINTAINERS entry, and while at it make the Makefile glob match scripts/Makefile itself, and add one matching the Kbuild.include file as well.
