lowmemorykiller: don't unregister notifier from atomic context 2010-12-28T18:35:56+00:00 Rabin Vincent rabin.vincent@stericsson.com 2010-09-09T05:18:21+00:00 8b31719041662bae54d9acbef4e8c907756cdb6c The lowmemorykiller registers an atomic notifier for notfication of when the task is freed. From this atomic notifier callback, it removes the atomic notifier via task_free_unregister(). This is incorrect because atomic_notifier_chain_unregister() calls syncronize_rcu(), which can sleep, which shouldn't be done from an atomic notifier. Fix this by registering the notifier during init, and only unregister it if the lowmemorykiller is unloaded.
