Subject: linux-next: manual merge of the md tree
Date: Wed, 15 Oct 2008 19:34:13 +1100	[thread overview]
Message-ID: <20081015193413.90ec9792.sfr@canb.auug.org.au> (raw)

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).
