Revision 9f3a2cb228c28606895d15f13b30d1f7402dc745 authored by Pavel Begunkov on 24 September 2021, 16:14:48 UTC, committed by Jens Axboe on 24 September 2021, 16:26:11 UTC
We don't retry short writes and so we would never get to async setup in io_write() in that case. Thus ret2 > 0 is always false and iov_iter_advance() is never used. Apparently, the same is found by Coverity, which complains on the code. Fixes: cd65869512ab ("io_uring: use iov_iter state save/restore helpers") Reported-by: Dave Jones <davej@codemonkey.org.uk> Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Link: https://lore.kernel.org/r/5b33e61034748ef1022766efc0fb8854cfcf749c.1632500058.git.asml.silence@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
