Subject: [for-linus][PATCH 0/4] tracing: Fixes for v6.6-rc3

Tracing fixes for v6.6-rc3:

- Make sure 32 bit applications using user events have aligned access when
  running on a 64 bit kernel.

- Add cond_resched in the loop that handles converting enums in print_fmt
  string is trace events.

- Fix premature wake ups of polling processes in the tracing ring buffer. When
  a task polls waiting for a percentage of the ring buffer to be filled, the
  writer still will wake it up at every event. Add the polling's percentage to
  the "shortest_full" list to tell the writer when to wake it up.

- For eventfs dir lookups on dynamic events, an event system's only event could
  be removed, leaving its dentry with no children. This is totally legitimate.
  But on eventfs_release() it must not access the children array, as it is only
  allocated when the dentry has children.
