Subject: [PATCH 041/141] mm: Fix fall-through warnings for Clang
Date: Fri, 20 Nov 2020 12:30:51 -0600 [thread overview]
Message-ID: <f5756988b8842a3f10008fbc5b0a654f828920a9.1605896059.git.gustavoars@kernel.org> (raw)
In-Reply-To: <cover.1605896059.git.gustavoars@kernel.org>
In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple
of warnings by explicitly adding a break statement instead of just letting
the code fall through to the next, and by adding a fallthrough
pseudo-keyword in places where the code is intended to fall through.
