Subject: [PATCH 14/34] btrfs: Remove fs_info from btrfs_remove_block_group
Date: Wed, 20 Jun 2018 15:48:56 +0300	[thread overview]
Message-ID: <1529498956-4241-15-git-send-email-nborisov@suse.com> (raw)
In-Reply-To: <1529498956-4241-1-git-send-email-nborisov@suse.com>

This function is always called with a valid transaction handle from
where we can reference fs_info. No functional changes.
