[PATCH 0/3 V3] xfs: allow logical-sector sized O_DIRECT for any fs sector size

[Eric Sandeen]

Ok once more with feeling.

Patchset to allow sub-fs-metadata-sector-sized DIOs.

I have (still) explicitly not changed XFS_IOC_DIOINFO output for now;
it still reports the actual minimum sizes and alignments which will
be allowed by the filesystem (and block layer beneath it).

Thanks,
-Eric
