io_uring: optimise fill_event() by inlining
There are three cases where we much care about performance of io_cqring_fill_event() -- flushing inline completions, iopoll and io_req_complete_post(). Inline a hot part of fill_event() into them. All others are not as important and we don't want to bloat binary for them, so add a noinline version of the function for all other use use cases. nops test(batch=32): 16.932 vs 17.822 KIOPS Signed-off-by:Pavel Begunkov <asml.silence@gmail.com> Link: https://lore.kernel.org/r/a11d59424bf4417aca33f5ec21008bb3b0ebd11e.1618101759.git.asml.silence@gmail.com Signed-off-by:
