Subject: [PATCH 01/27] aio: fix failure to put the file pointer
Date: Fri, 30 Nov 2018 09:56:20 -0700 [thread overview]

In-Reply-To: <20181130165646.27341-1-axboe@kernel.dk>
If the ioprio capability check fails, we return without putting
the file pointer.
Fixes: d9a08a9e616b ("fs: Add aio iopriority support")
