Subject: [PATCH 08/11] xfs: flag files as supporting buffered async reads
Date: Fri, 22 May 2020 14:23:08 -0600	[thread overview]
Message-ID: <20200522202311.10959-9-axboe@kernel.dk> (raw)
In-Reply-To: <20200522202311.10959-1-axboe@kernel.dk>

XFS uses generic_file_read_iter(), which already supports this.
