Merge tag 'trace-v6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- 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 in eventfs_release() it must not access the
children array, as it is only allocated when the dentry has children.
* tag 'trace-v6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
eventfs: Test for dentries array allocated in eventfs_release()
tracing/user_events: Align set_bit() address for all archs
tracing: relax trace_event_eval_update() execution with cond_resched()
ring-buffer: Update "shortest_full" in polling
