Subject: [PATCH v9 22/41] btrfs: handle REQ_OP_ZONE_APPEND as writing
Date: Fri, 30 Oct 2020 22:51:29 +0900	[thread overview]
Message-ID: <4f9bb21cb378fa0b123caf56c37c06dedccbbf1f.1604065695.git.naohiro.aota@wdc.com> (raw)
In-Reply-To: <d9a0a445560db3a9eb240c6535f8dd1bbd0abd96.1604065694.git.naohiro.aota@wdc.com>

ZONED btrfs uses REQ_OP_ZONE_APPEND bios for writing to actual devices. Let
btrfs_end_bio() and btrfs_op be aware of it.
