[GIT PULL] first set of SCSI patches for the 2.6.38 merge window

[James Bottomley]

This is a first set because we've got a postmerge tree waiting on block
and a few in the pending queue.  The current tranche has all been
incubated in linux-next for at least 5 days.

It's mostly driver updates: qla2, qla4, lpfc, mpt2sas, megaraid_sas,
iscsi and fcoe/libfc.  Plus there's a herculean cleanup of bfa and a
redesign of the tracing in zfcp.  The rest are assorted minor fixes and
cleanups, plus one attempt to plug a data corruption problem with a
specific set of arrays (this isn't marked for backport to stable yet,
because I want to try it out in the field first).

The patch is available here:

master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6.git
