LVM, fix mirror ctr table arguments

Commit Message

Jonthan Brassow July 29, 2009, 7:34 p.m. UTC

The device-mapper table is being constructed incorrectly WRT
the upstream kernel.  "block_on_error" is no longer an argument
to the log module, but rather the "features" section of the
mirror CTR table.

Also in this patch are the changes necessary to construct the
mapping tables for cluster mirroring - given the recent inclusion
of dm-log-userspace.

(Patch is '-p0' not '-p1'.)
