[PATCH] btrfs: Remove redundant initialization of slot

From: Jiapeng Chong
Date: Fri Dec 31 2021 - 07:24:17 EST


slot is being initialized to path->slots[0] but this is never
read as slot is overwritten later on. Remove the redundant
initialization.

Cleans up the following clang-analyzer warning:

fs/btrfs/tree-log.c:6125:7: warning: Value stored to 'slot' during its
initialization is never read [clang-analyzer-deadcode.DeadStores].
