[PATCH] Fix another dm and bio problem
From: Mark Haverkamp <markh@osdl.org>
This fixes a problem similar to the patch I submitted on 11/20
http://marc.theaimsgroup.com/?l=linux-kernel&m=106936439707962&w=2
In this case, though, the result is an:
"Incorrect number of segments after building list" message.
The macro __BVEC_START assumes a bi_idx of zero when the dm code can
submit a bio with a non-zero bi_idx.
The code has been tested on an 8 way / 8gb OSDL STP machine with a 197G
lvm volume running dbt2 test.
