Subject: [PATCH 03/15] btrfs: Remove  EXTENT_FIRST_DELALLOC bit
Date: Wed, 30 Jan 2019 16:50:50 +0200
Message-ID: <20190130145102.4708-4-nborisov@suse.com> (raw)
In-Reply-To: <20190130145102.4708-1-nborisov@suse.com>

With the refactoring introduced in 8b62f87bad9c ("Btrfs: reworki
outstanding_extents") this flag became unused. Remove it and renumber
the following flags accordingly. No functional changes.
