Revert "kernfs: remove KERNFS_ACTIVE_REF and add kernfs_lockdep()"
This reverts commit a69d001cfc712b96ec9d7ba44d6285702a38dabf. 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 <tj@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
