Both ext4 and xfs support per-inode DAX flag now so move it to generic.

/me wonders if this ought to be smart enough to sniff out the hugepage
size on the test machine...
Hi Darrick,
PMD page is always 2M, I am not sure why we need to sniff out the hugepage
size? Could you give me an example?
arm64, which can have 512M hugepages.
ppc64, which can have 16M huge pages (I think?)
Hi Darrick,
Sorry I don't understand what you mean.
I know different arches have different page size/hugepage size but I
don't know the relationship between PMD page fault and hugepage.
Accodring to dax.txt in kernel, it seems that we have to format block
device with a fixed block size which is equal to kernel's page size.
mount will fail or disable dax feature if block size is not equal to
kernel's page size, so do you mean this?
Best Regards,
Xiao Yang
