Revert "kernfs: remove unnecessary NULL check in __kernfs_remove()"
This reverts commit 88533f99. Tejun writes: I'm sorry but can you please revert the whole series? get_active() waiting while a node is deactivated has potential to lead to deadlock and that deactivate/reactivate interface is something fundamentally flawed and that cgroup will have to work with the remove_self() like everybody else. IOW, I think the first posting was correct. Cc: Tejun Heo <firstname.lastname@example.org> Signed-off-by: Greg Kroah-Hartman <email@example.com>
