Subject: affs: remove useless superblock writeout on remount
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0164b1a32e6849121ea73ef3124a2994951a4713;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

affs: remove useless superblock writeout on remount

We do not need to write out the superblock from '->remount_fs()' because
VFS has already called '->sync_fs()' by this time and the superblock has
already been written out. Thus, remove the 'affs_write_super()'
infocation from 'affs_remount()'.
