Subject: [PATCH 4/5][next] bcachefs: remove duplicated assignment to variable offset_into_extent
Date: Tue, 12 Sep 2023 13:37:43 +0100 [thread overview]
Message-ID: <20230912123744.3929609-5-colin.i.king@gmail.com> (raw)
In-Reply-To: <20230912123744.3929609-1-colin.i.king@gmail.com>
Variable offset_into_extent is being assigned to zero and a few
statements later it is being re-assigned again to the save value.
The second assignment is redundant and can be removed. Cleans up
clang-scan build warning:
fs/bcachefs/io.c:2722:3: warning: Value stored to 'offset_into_extent'
is never read [deadcode.DeadStores]
