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.
