From: Steve French Date: Tue, 31 Jul 2018 06:21:37 +0000 (-0500) Subject: cifs: simple stats should always be enabled X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fcabb89299d79010eb923afdd26de04afcc0527f;p=openwrt%2Fstaging%2Fblogic.git cifs: simple stats should always be enabled CONFIG_CIFS_STATS should always be enabled as Pavel recently noted. Simple statistics are not a significant performance hit, and removing the ifdef simplifies the code slightly.
