From 772d233f5dec86e38a96e58cc995e7b04ab4ec68 Mon Sep 17 00:00:00 2001 From: Zhao Lei Date: Mon, 24 Aug 2015 21:10:18 +0800 Subject: [PATCH] btrfs: Reset sblock->xxx_error stats before calling scrub_recheck_block_checksum We should reset sblock->xxx_error stats before calling scrub_recheck_block_checksum(). Current code run correctly because all sblock are allocated by k[cz]alloc(), and the error stats are not got changed.
