Subject: [PATCH 1/4] btrfs: remove unused member btrfs_root::name
Date: Fri, 20 Jul 2018 16:30:18 +0200	[thread overview]
Message-ID: <fb437253306a61e96a2871706778ee6c365ba9b5.1532096607.git.dsterba@suse.com> (raw)
In-Reply-To: <cover.1532096607.git.dsterba@suse.com>

Added in 58176a9604c ("Btrfs: Add per-root block accounting and sysfs
entries") in 2007, the roots had names exported in sysfs. The code
was commented out in 4df27c4d5cc1dda54ed ("Btrfs: change how subvolumes
are organized") and cleaned by 182608c8294b5fe9 ("btrfs: remove old
unused commented out code").
