Subject: affs: remove useless superblock writeout on unmount
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c9753b1d20e13c94d15a1c8b252a696744bd22a2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

affs: remove useless superblock writeout on unmount

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