From eee458936b52bd3a9ff0ff577313b637905fff08 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 3 Jul 2012 16:43:27 +0300 Subject: [PATCH] fs/sysv: remove another useless write_super call We do not need to call 'sysv_write_super()' from 'sysv_remount()', because VFS has called 'sysv_sync_fs()' before calling '->remount()'. So remove it. Remove also '(un)lock_super()' which obvioulsy is becoming useless in this function.
