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/scsi/scsi_error.c between commit
a953809f9d1deb97bb27716d773cadd2feebccf8 ("[SCSI] Log msg when getting
Unit Attention") from the scsi tree and commit
f9ccdfe846639f7a4529ccab78468b2207382380 ("scsi: use REQ_TYPE_FS for
flush request") from the block tree.

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