Subject: [PATCH v9 26/41] btrfs: enable zone append writing for direct IO
Date: Fri, 30 Oct 2020 22:51:33 +0900 [thread overview]
Message-ID: <0ac6b4d4630d97838ea6532ba81c8ebf1cfaffd3.1604065695.git.naohiro.aota@wdc.com> (raw)

Likewise to buffered IO, enable zone append writing for direct IO when its
used on a zoned block device.
