From 269ee27e99cfbff983a9ab067ae22f6182f11fe2 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Thu, 7 Feb 2019 13:13:57 -0600 Subject: [PATCH] nbd/server: Kill pointless shadowed variable lgtm.com pointed out that commit 678ba275 introduced a shadowed declaration of local variable 'bs'; thankfully, the inner 'bs' obtained by 'blk_bs(blk)' matches the outer one given that we had 'blk_insert_bs(blk, bs, errp)' a few lines earlier, and there are no later uses of 'bs' beyond the scope of the 'if (bitmap)' to care if we change the value stored in 'bs' while traveling the backing chain to find a bitmap. So simply get rid of the extra declaration.
