Subject: [PATCH] fs/aio.c: fix wrong return value regression in __io_submit_one
Date: Tue, 9 Apr 2019 14:06:50 +0800 [thread overview]
Message-ID: <20190409060650.28901-1-jencce.kernel@gmail.com> (raw)
Now it returns 0 when actually error happened, causing kernel hang easily.
Fixes: 7316b49 "aio: move sanity checks and request allocation to io_submit_one()"
