Subject: [PATCH 01/12] maple_tree: Remove unnecessary default labels from switch statements
Date: Wed, 1 Nov 2023 13:16:18 -0400 [thread overview]
Message-ID: <20231101171629.3612299-2-Liam.Howlett@oracle.com> (raw)
In-Reply-To: <20231101171629.3612299-1-Liam.Howlett@oracle.com>
Removing the default types from the switch statements will cause compile
warnings on missing cases.
Suggested-by: Andrew Morton <akpm@linux-foundation.org>
