v4->v5
- change the implementation of merge_wq_list
v5->v6
- change the logic of handling prior task list to:
1) grabbed uring_lock: leverage the inline completion infra
2) otherwise: batch __req_complete_post() calls to save
completion_lock operations.
v6->v7
- add Pavel's fix of wrong spin unlock
- remove a patch and rebase work
Hao Xu (5):
io-wq: add helper to merge two wq_lists
io_uring: add a priority tw list for irq completion work
io_uring: add helper for task work execution code
io_uring: split io_req_complete_post() and add a helper
io_uring: batch completion in prior_task_list
