[Devel] [PATCH hci-8.1 v4 08/11] dm-ploop: use wake_up() for inflight_md_wq and dispatcher_wq_prealloc

[Alexander Ivanov]

wake_up_interruptible() wakes only TASK_INTERRUPTIBLE waiters. All the
current waiters on inflight_md_wq and dispatcher_wq_prealloc sleep
interruptibly, but one of the next patches adds uninterruptible ones on
postsuspend, which would never be woken. Use wake_up(), which wakes
both kinds.
