The driver parses a union where the layout up through the first array is the same, however, the array has different sizes depending on the elements in the union. Be explicit to fix the UBSAN checker.

When we removed the hacky start code check we actually didn't took into account that *all* VRAM pages needs to be CPU accessible. Clean up the code and unify the handling into a single helper which checks if the whole resource is CPU accessible. The only place where a partial check would make sense is during eviction, but that is neglitible.

The majority of those where removed in the commit aed01a68 ("drm/amdgpu: Remove TTM resource->start visible VRAM condition v2") But this one was missed because it's working on the resource and not the BO. Since we also no longer use a fake start address for visible BOs this will now trigger invalid mapping errors. v2: also remove the unused variable Signed-off-by: Christian König <christian.koenig@amd.com> Fixes: aed01a68 ("drm/amdgpu: Remove TTM resource->start visible VRAM condition v2") CC: stable@vger.kernel.org Acked-by: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Pull sysfs fix from Al Viro: "Get rid of lockdep false positives around sysfs/overlayfs syzbot has uncovered a class of lockdep false positives for setups with sysfs being one of the backing layers in overlayfs. The root cause is that of->mutex allocated when opening a sysfs file read-only (which overlayfs might do) is confused with of->mutex of a file opened writable (held in write to sysfs file, which overlayfs won't do).

The writable file /sys/power/resume may call vfs lookup helpers for arbitrary paths and readonly files can be read by overlayfs from vfs helpers when sysfs is a lower layer of overalyfs. To avoid a lockdep warning of circular dependency between overlayfs inode lock and kernfs of->mutex, use a different lockdep class for writable and readonly kernfs files.

Even though the command duration limits (CDL) feature was first added in ACS-5 (major version 12), there are some ACS-4 (major version 11) drives that implement CDL as well. IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages are mandatory in the ACS-4 standard so it should be safe to read these log pages on older drives implementing the ACS-4 standard.

Commit 0c76106c ("scsi: sd: Fix TCG OPAL unlock on system resume") incorrectly handles failures of scsi_resume_device() in ata_scsi_dev_rescan(), leading to a double call to spin_unlock_irqrestore() to unlock a device port. Fix this by redefining the goto labels used in case of errors and only unlock the port scsi_scan_mutex when scsi_resume_device() fails.

Commit d96c3600 ("tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig entry") removed a hidden tab because it apparently showed breakage in some third-party kernel config parsing tool. It wasn't clear what tool it was, but let's make sure it gets fixed. Because if you can't parse tabs as whitespace, you should not be parsing the kernel Kconfig files. In fact, let's make such breakage more obvious than some esoteric ftrace record size option. If you can't parse tabs, you can't have page sizes. Yes, tab-vs-space confusion is sadly a traditional Unix thing, and 'make' is famous for being broken in this regard. But no, that does not mean that it's ok. I'd add more random tabs to our Kconfig files, but I don't want to make things uglier than necessary. But it *might* bbe necessary if it turns out we see more of this kind of silly tooling.

Pull tracing fixes from Steven Rostedt: - Fix the buffer_percent accounting as it is dependent on three variables: 1) pages_read - number of subbuffers read 2) pages_lost - number of subbuffers lost due to overwrite 3) pages_touched - number of pages that a writer entered These three counters only increment, and to know how many active pages there are on the buffer at any given time, the pages_read and pages_lost are subtracted from pages_touched. But the pages touched was incremented whenever any writer went to the next subbuffer even if it wasn't the only one, so it was incremented more than it should be causing the counter for how many subbuffers currently have content incorrect, which caused the buffer_percent that holds waiters until the ring buffer is filled to a given percentage to wake up early. - Fix warning of unused functions when PERF_EVENTS is not configured in - Replace bad tab with space in Kconfig for FTRACE_RECORD_RECURSION_SIZE - Fix to some kerneldoc function comments in eventfs code. * tag 'trace-v6.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Only update pages_touched when a new page is touched tracing: hide unused ftrace_event_id_fops tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig entry eventfs: Fix kernel-doc comments to functions

While monitoring the throttle time of IO from iocost, it's found that such time is always zero after the io_schedule() from ioc_rqos_throttle, for example, with the following debug patch: + printk("%s-%d: %s enter %llu\n", current->comm, current->pid, __func__, blk_time_get_ns()); while (true) { set_current_state(TASK_UNINTERRUPTIBLE); if (wait.committed) break; io_schedule(); } + printk("%s-%d: %s exit %llu\n", current->comm, current->pid, __func__, blk_time_get_ns()); It can be observerd that blk_time_get_ns() always return the same time: [ 1068.096579] fio-1268: ioc_rqos_throttle enter 1067901962288 [ 1068.272587] fio-1268: ioc_rqos_throttle exit 1067901962288 [ 1068.274389] fio-1268: ioc_rqos_throttle enter 1067901962288 [ 1068.472690] fio-1268: ioc_rqos_throttle exit 1067901962288 [ 1068.474485] fio-1268: ioc_rqos_throttle enter 1067901962288 [ 1068.672656] fio-1268: ioc_rqos_throttle exit 1067901962288 [ 1068.674451] fio-1268: ioc_rqos_throttle enter 1067901962288 [ 1068.872655] fio-1268: ioc_rqos_throttle exit 1067901962288 And I think the root cause is that 'PF_BLOCK_TS' is always cleared by blk_flush_plug() before scheduel(), hence blk_plug_invalidate_ts() will never be called: blk_time_get_ns plug->cur_ktime = ktime_get_ns(); current->flags |= PF_BLOCK_TS; io_schedule: io_schedule_prepare blk_flush_plug __blk_flush_plug /* the flag is cleared, while time is not */ current->flags &= ~PF_BLOCK_TS; schedule sched_update_worker /* the flag is not set, hence plug->cur_ktime is not cleared */ if (tsk->flags & PF_BLOCK_TS) blk_plug_invalidate_ts() blk_time_get_ns /* got the time stashed before schedule */ return plug->cur_ktime; Fix the problem by clearing cached time in __blk_flush_plug().

After commit 6d029c25 ("selftests/timers/posix_timers: Reimplement check_timer_distribution()"), clang warns: tools/testing/selftests/timers/../kselftest.h:398:6: warning: variable 'major' is used uninitialized whenever '||' condition is true [-Wsometimes-uninitialized] 398 | if (uname(&info) || sscanf(info.release, "%u.%u.", &major, &minor) != 2) | ^~~~~~~~~~~~ tools/testing/selftests/timers/../kselftest.h:401:9: note: uninitialized use occurs here 401 | return major > min_major || (major == min_major && minor >= min_minor); | ^~~~~ tools/testing/selftests/timers/../kselftest.h:398:6: note: remove the '||' if its condition is always false 398 | if (uname(&info) || sscanf(info.release, "%u.%u.", &major, &minor) != 2) | ^~~~~~~~~~~~~~~ tools/testing/selftests/timers/../kselftest.h:395:20: note: initialize the variable 'major' to silence this warning 395 | unsigned int major, minor; | ^ | = 0 This is a false positive because if uname() fails, ksft_exit_fail_msg() will be called, which unconditionally calls exit(), a noreturn function. However, clang does not know that ksft_exit_fail_msg() will call exit() at the point in the pipeline that the warning is emitted because inlining has not occurred, so it assumes control flow will resume normally after ksft_exit_fail_msg() is called. Make it clear to clang that all of the functions that call exit() unconditionally in kselftest.h are noreturn transitively by marking them explicitly with '__attribute__((__noreturn__))', which clears up the warning above and any future warnings that may appear for the same reason.

Commit 1a75cc71 ("iommu/vt-d: Use rbtree to track iommu probed devices") adds all devices probed by the iommu driver in a rbtree indexed by the source ID of each device. It assumes that each device has a unique source ID. This assumption is incorrect and the VT-d spec doesn't state this requirement either. The reason for using a rbtree to track devices is to look up the device with PCI bus and devfunc in the paths of handling ATS invalidation time out error and the PRI I/O page faults. Both are PCI ATS feature related. Only track the devices that have PCI ATS capabilities in the rbtree to avoid unnecessary WARN_ON in the iommu probe path. Otherwise, on some platforms below kernel splat will be displayed and the iommu probe results in failure.
