From: Yiwen Jiang <jiangyiwen@xxxxxxxxxx>
Subject: [PATCH] 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.
