Subject: [PATCH v4 17/27] btrfs: implement atomic compressed IO submission
Date: Fri, 23 Aug 2019 19:10:26 +0900	[thread overview]
Message-ID: <20190823101036.796932-18-naohiro.aota@wdc.com> (raw)
In-Reply-To: <20190823101036.796932-1-naohiro.aota@wdc.com>

As same as with non-compressed IO submission, we must unlock a block group
for the next allocation.
