Subject: fs/sysv: remove another useless write_super call
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eee458936b52bd3a9ff0ff577313b637905fff08;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

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.
