[PATCH V3 03/17] block: rename QUEUE_FLAG_NO_SCHED as QUEUE_FLAG_ADMIN

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now all users of QUEUE_FLAG_NO_SCHED is for admin queue only, and not
see any drivers need this flag for IO queue.

So rename it as QUEUE_FLAG_ADMIN, which looks more straightforward.
