Subject: [PATCH v3 17/27] btrfs: implement atomic compressed IO submission
Date: Thu, 8 Aug 2019 18:30:28 +0900 [thread overview]
Message-ID: <20190808093038.4163421-18-naohiro.aota@wdc.com> (raw)
In-Reply-To: <20190808093038.4163421-1-naohiro.aota@wdc.com>
As same as with non-compressed IO submission, we must unlock a block group
for the next allocation.
