Breno Leitao 6b1b324e96 selftests/configfs: race symlink against rmdir of the target
configfs_rmdir() drops the last reference to an item while its dentry is
still hashed, so a symlink(2) resolving that target takes a reference on
freed memory.  syzbot reported it [1].

Race mkdir/rmdir of a target against symlink/unlink of a link to it,
watching /sys/kernel/warn_count.

Fails until the fix [2] lands.
