Subject[PATCH -next v6 3/5] md/bitmap: always wake up md_thread in timeout_store
Date
From: Yu Kuai <yukuai3@huawei.com>

md_wakeup_thread() can handle the case that pass in md_thread is NULL,
the only difference is that md_wakeup_thread() will be called when
current timeout is 'MAX_SCHEDULE_TIMEOUT', this should not matter
because timeout_store() is not hot path, and the daemon process is
woke up more than demand from other context already.

This patch prepare to factor out a helper to set timeout.
