Commit 254f796b9f22b1944c64caabc356a56caaa2facd updated
the driver to use 16 MSI-X vectors, despite the fact that
older controllers would provide only 4.
This was causing MSI-X registration to drop down to INTx
mode. But as the controller support performant mode, the

This is a big patch series. Most of the changes have to do
with enabling alternate command submission paths for certain i/os
to bypass the Smart Array RAID firmware stack and submit i/o's
more directly to physical devices -- solid state disks --
for increased performance.

When commands sent down the "fast path" fail, they must be re-tried down the
normal RAID path. We do this by kicking i/o's back to the scsi mid layer with
a DID_SOFT_ERROR status, which causes them to be retried. This won't work for
SG_IO's and other non REQ_TYPE_FS i/o
From: Matt Gates
For certain i/o's to certain devices (unmasked physical disks) we
can bypass the RAID stack firmware and do the i/o to the device
directly and it will be faster.

Hey,
I stumbled on a nasty crash with 3.14-rc1 when playing with scsi_debug
DIF emulation.
It's late (IL time..), so I thought I'd post this one up and ask if
anyone else noticed it before digging into this one.
it comes from the condition:
