Subject: [PATCH 05/11] btrfs: Make btrfs_pin_reserved_extent take transaction
Date: Mon, 20 Jan 2020 16:09:12 +0200	[thread overview]
Message-ID: <20200120140918.15647-6-nborisov@suse.com> (raw)
In-Reply-To: <20200120140918.15647-1-nborisov@suse.com>

btrfs_pin_reserved_extent is now only called with a valid transaction so
exploit the fact to take a transaction. This is preparation for tracking
pinned extents on a per-transaction basis.
