Subject: [PATCH] Revert "kernfs: make kernfs_get_active() block if the node is
 deactivated but not removed"

This reverts commit 895a068a524e134900b9d98b519309b7aae7bbb1.

        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.
