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.

Hi Alexander Viro and Eric,
My patch has already sent two weeks, but nobody help me
to review, I have a question about now who is the v9fs's
maintainer? Or who can help me review the patch?
I hope v9fs's maintainer can give me some advices or
merge into the mainline if it has no problem.
Thanks,
Yiwen.

Hi Andrew,
My patch has already sent more than two weeks, but nobody
help me to review, I have a question about now who is the
v9fs's maintainer? Or who can help me review the patch?
I hope v9fs's maintainer can give me some advices or
merge into the mainline if it has no problem.
Thanks,
Yiwen.
Hi,
I think you would better to modify the subject line without
[V9fs-developers].
