Subject: [PATCH 8/8] btrfs: turn on -Wmaybe-uninitialized
Date: Fri, 16 Dec 2022 15:15:58 -0500	[thread overview]
Message-ID: <1d9deaa274c13665eca60dee0ccbc4b56b506d06.1671221596.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1671221596.git.josef@toxicpanda.com>

We had a recent bug that would have been caught by a newer compiler with
-Wmaybe-uninitialized and would have saved us a month of failing tests
that I didn't have time to investigate.
