[GIT PULL] final round of SCSI updates for the 5.2+ merge window

[GIT PULL] final round of SCSI updates for the 5.2+ merge window

[James Bottomley]

This is the final round of mostly small fixes in our initial
submit.  It's mostly minor fixes and driver updates.  The only change
of note is adding a virt_boundary_mask to the SCSI host and host
template to parametrise this for NVMe devices instead of having them do
a call in slave_alloc.  It's a fairly straightforward conversion except
in the two NVMe handling drivers that didn't set it who now have a
virtual infinity parameter added.

The patch is available here:

It has been observed on NVMe the above approach("take the DMA max
mapping size into account") causes performance regression, so I'd
suggest to fix dma_max_mapping_size() first.

Christoph has posted fix already, but looks not merged yet:

Christoph specifically asked me to queue these up. I presume the swiotlb
tweak is going through his DMA tree and it is therefore orthogonal to
the SCSI changes.

I do think it's important that we get these fixed up in 5.3. And given
that we're on the eve of the merge window, the time to get these changes
merged is now. I'd hate to see them miss another release...
