Xen and EVMS/Raid5 - Null pointer dereference
Hi,
A problem with EVMS and Xen:
I have patched a 2.6 kernel with the evms patches and then with the Xen patched, compiled and installed it. (kernel is 2.6.11.9 - which is what this server has been running for the past few months w/o the evms patches)
At first everything seems to work just fine, I am able to use evms to create a new "volume", in this case it is based on MD/RAID-5 but

xen, lvm, drbd, bad kernel messages
Regardless of the filesystem (i''ve used reiserfs, xfs, ext3),
whenever I mount a fresh DRBD partition I get some nasty kernel
messages.
This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using
DRBD v0.7.11 (pulled from Debian "testing").
This is what I did to create the partition.
On both nodes I created a new LVM storage device and started DRBD:
# lvcreate

[PATCH 07/22] block: Convert bio_for_each_segment() to bvec_iter
More prep work for immutable biovecs - with immutable bvecs drivers
won't be able to use the biovec directly, they'll need to use helpers
that take into account bio->bi_iter.bi_bvec_done.
This updates callers for the new usage without changing the
implementation yet.
