Subject: [PATCH 03/14] btrfs: qgroup: Make qgroup_reserve and its callers to use separate reservation type
Date: Tue, 12 Dec 2017 15:34:25 +0800	[thread overview]
Message-ID: <20171212073436.16447-4-wqu@suse.com> (raw)
In-Reply-To: <20171212073436.16447-1-wqu@suse.com>

Since most caller of qgroup_reserve() is already defined by type,
converting qgroup_reserve() is quite an easy work.
