Subject[V9fs-developer] [PATCH] fs/9p: don't set SB_NOATIME by default
Date
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.
