User use some syscall, for example mmap(v9fs_file_mmap), it will not update atime even if user's mnt_flags without MNT_NOATIME, because v9fs default set SB_NOATIME in v9fs_set_super. For supporting access time is updated when user mount with relatime, we should not set SB_NOATIME by default. Sign

User use some syscall, for example mmap(v9fs_file_mmap), it will not update atime even if user's mnt_flags have MNT_NOATIME, because v9fs default set SB_NOATIME in v9fs_set_super. For supporting access time is updated when user mount with relatime, we should clear SB_NOATIME by default. Signed-of
