[for-linus][PATCH 0/2] eventfs: Fixes for v6.7-rc2

[Steven Rostedt <rostedt@goodmis.org>]

A couple of fixes to eventfs:

- With the usage of simple_recursive_remove() recommended by Al Viro,
  the code should not be calling "d_invalidate()" itself. Doing so
  is causing crashes. The code was calling d_invalidate() on the race
  of trying to look up a file while the parent was being deleted.
  This was detected, and the added dentry was having d_invalidate() called
  on it, but the deletion of the directory was also calling d_invalidate()
  on that same dentry.

- A fix to not free the eventfs_inode (ei) until the last dput() was called
  on its ei->dentry made the ei->dentry exist even after it was marked
  for free by setting the ei->is_freed. But code elsewhere still was
  checking if ei->dentry was NULL if ei->is_freed is set and would
  trigger WARN_ON if that was the case. That's no longer true and there
  should not be any warnings when it is true.

Steven Rostedt (Google) (2):
      eventfs: Remove expectation that ei->is_freed means ei->dentry == NULL
      eventfs: Do not invalidate dentry in create_file/dir_dentry()
