kernel/linux.git/io_uring/rw.h, branch v6.6.132Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.6.1322023-06-02T14:55:37+00:00io_uring: avoid indirect function calls for the hottest task_work2023-06-02T14:55:37+00:00Jens Axboeaxboe@kernel.dk2023-06-02T14:41:46+00:00urn:sha1:c92fcfc2bab54451c4f1481755ea244f413455cb
We use task_work for a variety of reasons, but doing completions or
triggering rety after poll are by far the hottest two. Use the indirect
funtion call wrappers to avoid the indirect function call if
CONFIG_RETPOLINE is set.

io_uring/rw: don't lose partial IO result on fail2022-09-21T19:15:02+00:00Pavel Begunkovasml.silence@gmail.com2022-09-21T11:17:47+00:00urn:sha1:47b4c68660752facfa6247b1fc9ca9d722b8b601
A partially done read/write may end up in io_req_complete_failed() and
loose the result, make sure we return the number of bytes processed.
