Hi Guys,

The multipage bvec patchset[1] has been posted out for a while, and
xfstest(ext4, xfs and btrfs) have been run and no regression is
observed, and I hope having talk about this in person would help
moving it forward.

Secondly I'd like to discuss with guys about the following next steps
of mp-bvec:

1) cleanup raid1/raid5/raid10 for removing the only singlepage bvec path

Hi Ming,

I am interested on this topic. Could you please provide a hint that what
is the proper way to remove single page bvec from md raid code ? And
will dm code involved in as well ?

Thanks.
