From: Dave Olien <dmo@osdl.org>
This patch applies to the 2.6.11-rc3-mm2 patch set. It is dependent
upon the mm2 patches:
add-local-bio-pool-support-and-modify-dm.patch
add-local-bio-pool-support-and-modify-dm-uninline-zero_fill_bio.patch
It just changes bio_clone() to use the global bio_set pool instead of the
bio_set pool associated with the bio argument. This is because raid5
and raid6 bio's are not allocated from a bio_set and have no bio_set
associated with them. This patch along with the patch Linux just accepted
allows raid5 and raid6 to function.
