Re: [dm-devel] [Bcache v13 01/16] Only clone bio vecs that are in use

[Kent Overstreet <koverstreet-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>]

Oh, I never got around to figuring out what needed to be done with the
bio integrity - presumably it'll have to be handled differently
somehow (I'm assuming an index in the integrity bvec is intended to
match up with an index in the regular bvec), but I don't have any way
to test the integrity stuff.
