Subject: [PULL 05/56] block/vdi: Clean up local variable shadowing
Date: Fri, 29 Sep 2023 10:50:02 +0200 [thread overview]
Message-ID: <20230929085053.2789105-6-armbru@redhat.com> (raw)
In-Reply-To: <20230929085053.2789105-1-armbru@redhat.com>
Local variables shadowing other local variables or parameters make the
code needlessly hard to understand. Tracked down with -Wshadow=local.
Clean up: delete inner declarations when they are actually redundant,
else rename variables.
