      fscache_create_volume_work() uses wake_up_bit() to wake up the processes
      which are waiting for the completion of volume creation. According to
      comments in wake_up_bit() and waitqueue_active(), an extra smp_mb() is
      needed to guarantee the memory order between FSCACHE_VOLUME_CREATING
      flag and waitqueue_active() before invoking wake_up_bit().
      
      Fixing it by using clear_and_wake_up_bit() to add the missing memory
      barrier.

      fscache: Use wait_on_bit() to wait for the freeing of relinquished volume · 8226e37d
      Hou Tao authored
      The freeing of relinquished volume will wake up the pending volume
      acquisition by using wake_up_bit(), however it is mismatched with
      wait_var_event() used in fscache_wait_on_volume_collision() and it will
      never wake up the waiter in the wait-queue because these two functions
      operate on different wait-queues.
      
      According to the implementation in fscache_wait_on_volume_collision(),
      if the wake-up of pending acquisition is delayed longer than 20 seconds
      (e.g., due to the delay of on-demand fd closing), the first
      wait_var_event_timeout() will timeout and the following wait_var_event()
      will hang forever as shown below:
      
       FS-Cache: Potential volume collision new=00000024 old=00000022
       ......

      Considering that wake_up_bit() is more selective, so fix it by using
      wait_on_bit() instead of wait_var_event() to wait for the freeing of
      relinquished volume. In addition because waitqueue_active() is used in
      wake_up_bit() and clear_bit() doesn't imply any memory barrier, use
      clear_and_wake_up_bit() to add the missing memory barrier between
      cursor->flags and waitqueue_active().

      This reverts commit 7efc3b72.
      
      We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
      stalling CPU for long periods of time.  Investigation of tracepoint data
      shows that compaction is stuck in repeating fast_find_migrateblock()
      based migrate page isolation, and then fails to migrate all isolated
      pages.
      
      Commit 7efc3b72 ("mm/compaction: fix set skip in fast_find_migrateblock")
      was suspected as it was merged in 6.1 and in theory can indeed remove a
      termination condition for fast_find_migrateblock() under certain
      conditions, as it removes a place that always marks a scanned pageblock
      from being re-scanned.  There are other such places, but those can be
      skipped under certain conditions, which seems to match the tracepoint
      data.
      
      Testing of revert also appears to have resolved the issue, thus revert
      the commit until a more robust solution for the original problem is
      developed.
      
      It's also likely this will fix qemu stalls with 6.1 kernel reported in
      Link 2, but that is not yet confirmed.

      Joe found another DT file that shouldn't be executable, and that

              cut -f2 |
              xargs grep -L '^#!'
      
      and that found another file that shouldn't have been marked executable
      either, despite being in the scripts directory.
      
      Maybe these two are the last ones at least for now.  But I'm sure we'll
      be back in a few years, fixing things up again.

      ovl: fail on invalid uid/gid mapping at copy up · 4f11ada1
      Miklos Szeredi authored
      If st_uid/st_gid doesn't have a mapping in the mounter's user_ns, then
      copy-up should fail, just like it would fail if the mounter task was doing
      the copy using "cp -a".
      
      There's a corner case where the "cp -a" would succeed but copy up fail: if
      there's a mapping of the invalid uid/gid (65534 by default) in the user
      namespace.  This is because stat(2) will return this value if the mapping
      doesn't exist in the current user_ns and "cp -a" will in turn be able to
      create a file with this uid/gid.
      
      This behavior would be inconsistent with POSIX ACL's, which return -1 for
      invalid uid/gid which result in a failed copy.
      
      For consistency and simplicity fail the copy of the st_uid/st_gid are
      invalid.

      io_uring: always prep_async for drain requests · ef5c600a
      Dylan Yudaken authored
      Drain requests all go through io_drain_req, which has a quick exit in case
      there is nothing pending (ie the drain is not useful). In that case it can
      run the issue the request immediately.
      
      However for safety it queues it through task work.
      The problem is that in this case the request is run asynchronously, but
      the async work has not been prepared through io_req_prep_async.
      
      This has not been a problem up to now, as the task work always would run
      before returning to userspace, and so the user would not have a chance to
      race with it.
      
      However - with IORING_SETUP_DEFER_TASKRUN - this is no longer the case and
      the work might be defered, giving userspace a chance to change data being
      referred to in the request.
      
      Instead _always_ prep_async for drain requests, which is simpler anyway
      and removes this issue.

      tools: gpio: fix -c option of gpio-event-mon · 677d85e1
      Ivo Borisov Shopov authored
      Following line should listen for a rising edge and exit after the first
      one since '-c 1' is provided.
      
          # gpio-event-mon -n gpiochip1 -o 0 -r -c 1
      
      It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the
      above command doesn't exit after the first rising edge it keep listening
      for an event forever. The '-c 1' is not taken into an account.
      The problem is in commit 62757c32 ("tools: gpio: add multi-line
      monitoring to gpio-event-mon").
      Before this commit the iterator 'i' in monitor_device() is used for
      counting of the events (loops). In the case of the above command (-c 1)
      we should start from 0 and increment 'i' only ones and hit the 'break'
      statement and exit the process. But after the above commit counting
      doesn't start from 0, it start from 1 when we listen on one line.
      It is because 'i' is used from one more purpose, counting of lines
      (num_lines) and it isn't restore to 0 after following code
      
          for (i = 0; i < num_lines; i++)
              gpiotools_set_bit(&values.mask, i);
      
      Restore the initial value of the iterator to 0 in order to allow counting
      of loops to work for any cases.

      treewide: fix up files incorrectly marked executable · 262b42e0
      Linus Torvalds authored
      I'm not exactly clear on what strange workflow causes people to do it,
      but clearly occasionally some files end up being committed as executable
      even though they clearly aren't.
      
      This is a reprise of commit 90fda63f
      
       ("treewide: fix up files
      incorrectly marked executable"), just with a different set of files (but
      with the same trivial shell scripting).
      
      So apparently we need to re-do this every five years or so, and Joe
      needs to just keep reminding me to do so ;)
