[PATCH v2 0/2] new struct io_work and use it in f2fs fsverity work

Many works will go to submit_bio(). In many cases, the default
io priority of kworker cannot meet the real-time requirements of
the work. Such as f2fs_verify_bio work.

If a high-task-priority process reads the verity-file, it is
possible that the high-task-priority process will be slowly
because the kworker's io priority is too low.

A new work struct containing io priority can solve this problem.

Yi Sun (2):
workqueue: new struct io_work
f2fs: set io priority for fsverity work
