    That may not be the end of it. Slub also calls sysfs from sysfs_add_alias
    while holding slub_lock.

    If sysfs allows user space stuff to run then you cannot really hold any
    locks. How is one supposed to sync adding pointers to sysfs structures in
    subsystems? Drop all locks and then recheck the memory structures after
    the sysfs function returns? Awkward.
