From: Yiwen Jiang <jiangyiwen@xxxxxxxxxx> Subject: fs/9p: don't set SB_NOATIME by default When the user uses some syscall, for example mmap(v9fs_file_mmap), it will not update atime even if user's was set mnt_flags without MNT_NOATIME, because v9fs defaults to settine SB_NOATIME in v9fs_set_super. For supporting access time updating when the user mounts with relatime, we should not set SB_NOATIME by default.
