Pull btrfs reverts from David Sterba: "Due to a recent report [1] we need to revert the radix tree to xarray conversion patches. There's a problem with sleeping under spinlock, when xa_insert could allocate memory under pressure. We use GFP_NOFS so this is a real problem that we unfortunately did not discover during review. I'm sorry to do such change at rc6 time but the revert is IMO the safer option, there are patches to use mutex instead of the spin locks but that would need more testing. The revert branch has been tested on a few setups, all seem ok. The conversion to xarray will be revisited in the future" Link: https://lore.kernel.org/linux-btrfs/cover.1657097693.git.fdmanana@suse.com/ [1] * tag 'for-5.19-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: Revert "btrfs: turn delayed_nodes_tree into an XArray" Revert "btrfs: turn name_cache radix tree into XArray in send_ctx" Revert "btrfs: turn fs_info member buffer_radix into XArray" Revert "btrfs: turn fs_roots_radix in btrfs_fs_info into an XArray"

Currently the jitter mechanism will require two timer ticks per iteration, and it requires N iterations per bit. This N is determined with a small measurement, and if it's too big, it won't waste time with jitter entropy because it'd take too long or not have sufficient entropy anyway. With the current max N of 32, there are large timeouts on systems with a small CONFIG_HZ. Rather than set that maximum to 32, instead choose a factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for different configurations of CONFIG_HZ.

Instead of doing complicated calculations to find the size of the subroutines (which are even more complicated because they need to be stringified into an asm statement), just hardcode to 16. It is less dense for a few combinations of IBT/SLS/retbleed, but it has the advantage of being really simple.

The console_stop() and console_start() functions call pr_flush(). When suspending, these functions are called by the serial subsystem while the serial port is suspended. In this scenario, if there are any pending messages, a call to pr_flush() will always result in a timeout because the serial port cannot make forward progress. This causes longer suspend and resume times. Add a check in pr_flush() so that it will immediately timeout if the consoles are suspended.

The AP bus's __verify_queue_reservations function increments the ref count for the device driver passed in as a parameter, but fails to decrement it before returning control to the caller. This will prevents any subsequent removal of the module.

Building with UBSAN_DIV_ZERO with clang produces numerous fallthrough warnings from objtool. In the case of uncheck division, UBSAN_DIV_ZERO may introduce new control flow to check for division by zero. Because the result of the division is undefined, LLVM may optimize the control flow such that after the call to __ubsan_handle_divrem_overflow doesn't matter. If panic_on_warn was set, __ubsan_handle_divrem_overflow would panic. The problem is is that panic_on_warn is run time configurable. If it's disabled, then we cannot guarantee that we will be able to recover safely. Disable this config for clang until we can come up with a solution in LLVM.

This reverts commit 4a57a840. Dave Chinner reports: "As I suspected would occur, this change causes test failures. e.g generic/517 in fstests fails with: generic/517 1s ... - output mismatch [..] -deduped 131172/131172 bytes at offset 65536 +deduped 131072/131172 bytes at offset 65536" can you please revert this commit for the 5.19 series to give us more time to investigate and consider the impact of the the API change on userspace applications before we commit to changing the API" That changed return value seems to reflect reality, but with the fstest change, let's revert for now.

Pull networking fixes from Jakub Kicinski: "Including fixes from netfilter, bpf and wireless. Still no major regressions, the release continues to be calm. An uptick of fixes this time around due to trivial data race fixes and patches flowing down from subtrees. There has been a few driver fixes (particularly a few fixes for false positives due to 66e4c8d9 which went into -next in May!) that make me worry the wide testing is not exactly fully through. So "calm" but not "let's just cut the final ASAP" vibes over here.

Commit 3a0cf7ab ("ACPI: video: Change how we determine if brightness key-presses are handled") made acpi_video_handles_brightness_key_presses() report false when none of the ACPI Video Devices support backlight control. But it turns out that at least on a Dell Inspiron N4010 there is no ACPI backlight control, yet brightness hotkeys are still reported through the ACPI Video Bus; and since acpi_video_handles_brightness_key_presses() now returns false, brightness keypresses are now reported twice. To fix this rename the has_backlight flag to may_report_brightness_keys and also set it the first time a brightness key press event is received. Depending on the delivery of the other ACPI (WMI) event vs the ACPI Video Bus event this means that the first brightness key press might still get reported twice, but all further keypresses will be filtered as before. Note that this relies on other drivers reporting brightness key events calling acpi_video_handles_brightness_key_presses() when delivering the events (rather then once during driver probe). This is already required and documented in include/acpi/video.h: /* * Note: The value returned by acpi_video_handles_brightness_key_presses() * may change over time and should not be cached. */ Fixes: 3a0cf7ab ("ACPI: video: Change how we determine if brightness key-presses are handled") Link: https://lore.kernel.org/regressions/CALF=6jEe5G8+r1Wo0vvz4GjNQQhdkLT5p8uCHn6ZXhg4nsOWow@mail.gmail.com/Reported-and-tested-by: Ben Greening <bgreening@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Rafael J.
