*	io_uring: allow 0 length for buffer select	Dylan Yudaken	2022-07-25	1	-2/+2
\| \| \| \| \| \| \| \|	If user gives 0 for length, we can set it from the available buffer size. Signed-off-by: Dylan Yudaken <dylany@fb.com> Link: https://lore.kernel.org/r/20220630091231.1456789-2-dylany@fb.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
*	io_uring: kbuf: inline io_kbuf_recycle_ring()	Hao Xu	2022-07-25	1	-28/+0
\| \| \| \| \| \| \| \| \|	Make io_kbuf_recycle_ring() inline since it is the fast path of provided buffer. Signed-off-by: Hao Xu <howeyxu@tencent.com> Link: https://lore.kernel.org/r/20220623130126.179232-1-hao.xu@linux.dev Signed-off-by: Jens Axboe <axboe@kernel.dk>
*	io_uring: kbuf: kill __io_kbuf_recycle()	Hao Xu	2022-07-25	1	-29/+42
\| \| \| \| \| \| \| \| \|	__io_kbuf_recycle() is only called in io_kbuf_recycle(). Kill it and tweak the code so that the legacy pbuf and ring pbuf code become clear Signed-off-by: Hao Xu <howeyxu@tencent.com> Link: https://lore.kernel.org/r/20220622055551.642370-1-hao.xu@linux.dev Signed-off-by: Jens Axboe <axboe@kernel.dk>
*	io_uring: kill extra io_uring_types.h includes	Pavel Begunkov	2022-07-25	1	-1/+0
\| \| \| \| \| \| \| \| \| \|	io_uring/io_uring.h already includes io_uring_types.h, no need to include it every time. Kill it in a bunch of places, it prepares us for following patches.
