From 93b4e74789dbdefcffc7baac107069e74d98513c Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 17 Mar 2022 23:46:46 +0000 Subject: [PATCH] xen-blkback: remove redundant assignment to variable i MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Variable i is being assigned a value that is never read, it is being re-assigned later in a for-loop. The assignment is redundant and can be removed.
