This is really just putting together two eventfs patches that were
stepping on each other in conflicts. I decided to rip out the free_ei()
part into its own patch (as that was what was confliciting.

This series is just a combination of:

and

 https://lore.kernel.org/linux-trace-kernel/20231031113627.2edfa83f@gandalf.local.home/

With the stripped out free_ei() patch.

Steven Rostedt (Google) (3):
      eventfs: Have a free_ei() that just frees the eventfs_inode
      eventfs: Test for ei->is_freed when accessing ei->dentry
      eventfs: Save ownership and mode
