[dm-devel] [PATCH 3/9] dm: Introduce signal_pending_state()

[Bart Van Assche]

Use signal_pending_state() instead of open-coding it. This patch does
not change any functionality but makes it possible to pass TASK_KILLABLE
as the second argument of dm_wait_for_completion(). See also commit
16882c1e962b ("sched: fix TASK_WAKEKILL vs SIGKILL race").
