You requested me to move a BUG_ON() earlier (before the actual memory
allocation), and to update documentation. I'm quite in a hurry on other things,
so I'm delaying this (especially the documentation part for which I feel like a
new paragraph is needed).

You may look at the retry loop in configfs_rmdir() and see that locks need only
to be taken inside the loop, not outside. This would result in fewer lines for
exactly the same behavior.

Sorry for not being responsive enough. As mentioned above, I have more urgent
things to work on right now.
