[GIT PULL] tracefs: Updates for v7.3

Linus,

tracefs updates for v7.3:

- Define event fields before directory creation

  Move the event_define_fields() call in event_create_dir() before the
  eventfs directory creation. Previously, a failure after directory
  creation wouldn't clean up eventfs_inode because the error path didn't
  call eventfs_remove_dir(). This eliminates the need to clean up the
  eventfs directories if event_define_fields() fails.

- Add warning for out of bounds pos in __eventfs_iterate()

  Sashiko complains about the ctx->pos causing issues if it is less than 2
  or greater than MAX_INT in __eventfs_iterate(). The thing is, the logic
  prevents that from happening. But to make Sashiko happy, add a WARN_ON()
  and exit safely if the function ever does get input that is out of the
  range the function expects.
