[PATCH 0/3] io_uring/uring_cmd: avoid double indirect call in task work dispatch

[Caleb Sander Mateos <csander@purestorage.com>]

Define a io_req_tw_func_t wrapper function around each io_uring_cmd_tw_t
function to avoid the additional indirect call and save 8 bytes in
struct io_uring_cmd. Additionally avoid the io_should_terminate_tw()
computation in uring_cmd task work callbacks that don't need it.

Caleb Sander Mateos (3):
  io_uring: expose io_should_terminate_tw()
  io_uring/uring_cmd: call io_should_terminate_tw() when needed
  io_uring/uring_cmd: avoid double indirect call in task work dispatch
