Hi Jens,
Today's linux-next merge of the block tree got a conflict in
drivers/md/raid5.c between commit 37c61ff31e9b ("raid5: set bio bi_vcnt 0
for discard request") from Linus' tree and commit ed2d2f9a8265 ("block:
Abstract out bvec iterator") from the block tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
