Matt, Alex,

Here is an updated series for the DMA UNMAP length problem.
As before, it is built on Alex' vfio-next tree, and contains
two small fixes identified while testing this.

Changelog:
v1->v2:
 - [MR] Rework the boundary checking of page_array_iova_pinned,
   to compare against pfns instead of iovas.
 - [MR] Add r-b to Patch 2 (Thank you!)
 - [EF] (NEW) Noticed a missing return code check in the close routine
v1: https://lore.kernel.org/r/20220726150123.2567761-1-farman@linux.ibm.com/

Eric Farman (3):
  vfio/ccw: Add length to DMA_UNMAP checks
  vfio/ccw: Remove FSM Close from remove handlers
  vfio/ccw: Check return code from subchannel quiesce
