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")
