- 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.
FYI, took 5/6 into another patchset to avoid conflicts.
also, you can remove "[pavel: ...]" from patches, I was just
leaving them as a hint that the patches were very slightly
modified. I'll retest/etc. once you fix 6/6. Hopefully, will
be merged soon, the patches already had been bouncing around
for too long.
Gotcha.
Hao Xu (6):
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: move up io_put_kbuf() and io_put_rw_kbuf()
io_uring: batch completion in prior_task_list
