SubjectRE: linux-next: manual merge of the block tree with the scsi tree
Jens,

I have verified those conflict fixed by Stephen R. It is just context changes. OK to patch it if it is not patched to mainline.

Subject: linux-next: manual merge of the block tree with the scsi tree
Hi Jens,

Today's linux-next merge of the block tree got a conflict in
drivers/message/fusion/mptsas.c between commits
14d0f0b063f5363984dd305a792854f9c23e9e97 ("[SCSI] mpt fusion: Fixing 1078
data corruption issue for 36GB memory region") and
2f187862e579f1f5e883188cab6bd867cb60387f ("[SCSI] mpt fusion: Code
Cleanup patch") from the scsi tree and commit
b0790410300abaaf4f25f702803beff701baebf1 ("block: cleanup rq->data_len
usages") from the block tree.

Just context changes. I fixed it up (see below) and can carry the fix as
necessary.
