Subject: [PATCH v11 26/40] btrfs: enable zone append writing for direct IO
Date: Tue, 22 Dec 2020 12:49:19 +0900 [thread overview]
Message-ID: <bea1e8c8229bbb0cb3ae3eb63f0f163c678a305b.1608608848.git.naohiro.aota@wdc.com> (raw)
In-Reply-To: <06add214bc16ef08214de1594ecdfcc4cdcdbd78.1608608848.git.naohiro.aota@wdc.com>
Likewise to buffered IO, enable zone append writing for direct IO when its
used on a zoned block device.
