Steven Rostedt (Google) 04204cd9b0 eventfs: Add WARN_ON_ONCE() to checks in eventfs_root_lookup()
There's a couple of if statements in eventfs_root_lookup() that should
never be true. Instead of removing them, add WARN_ON_ONCE() around them.

  One is a tracefs_inode not being for eventfs.

  The other is a child being freed but still on the parent's children
  list. When a child is freed, it is removed from the list under the
  same mutex that is held during the iteration.
