Hmm that's odd, I have no changes in blk-merge.c in my tree against
Linus'. But you can pull:
git://git.kernel.dk/linux-2.6-block.git for-linus
Jens Axboe (2):
cciss: remove 30 second initial timeout on controller reset
block: fix missing bio back/front segment size setting in blk_recount_segments()
Kris Shannon (1):
Fix kernel NULL pointer dereference in xen-blkfront
Roel Kluin (1):
loop: don't increment p->offset with (size_t) -EINVAL
