Hi Neil,

Today's linux-next merge of the md tree got a conflict in
drivers/md/linear.c between commits
c9959059161ddd7bf4670cf47367033d6b2f79c4 ("block: fix diskstats access")
and 6feef531f55cf4a20fd9eb39f5352e5745203603 ("block: mark bio_split_pool
static") from Linus' tree and commit
2bc5b53551d8246e18562fa8e0cf5fe64b5f8184 ("md: linear: Represent
dev_info->size and dev_info->offset in sectors") from the md tree.

Just overlapping changes.  I fixed it up (see below).

Hi Neil,

Today's linux-next merge of the md tree got a conflict in drivers/md/md.c
between commit d8ade4ef35e2ae74b4d4b012eacd16ac1c34ad50 ("remove
CONFIG_KMOD from drivers") from the rr tree and commit
6caa3b0bbdb474647f6bdd8a958ffc46f78d8d58 ("md: Remove unnecessary
#includes, #defines, and function declarations") from the md tree.

Overlapping removals. I fixed it up (see below) and can carry the fix.

Thanks.
I pushed out a new for-next just a couple of hours before I got this
email which resolves that, so the conflict should disappear in your
next merge.

Thanks for that. Unfortunately, neil.brown.name was unresolvable this
morning so it will have to wait for tomorrow.

Actually I just managed to fetch it now, so it will make today's tree (if
I finish it :-().
