Tim - Thanks for the update.

This was kind of buried above, but we also need this commit picked up as
well to avoid a regression:

  Device shutdown notification for CAPI Flash cards

Status in linux package in Ubuntu:
Status in linux source package in Xenial:
  In Progress

Bug description:
  ---Problem Description---
  Some CAPI Flash cards need notification of device shutdown
  in order to flush pending I/Os.

  A PCI notification hook for shutdown has been added where
  the driver notifies the card and returns. When the device
  is removed in the PCI remove path, this code will wait for
  shutdown processing to complete. It could take a minimum of
  1 second for shutdown processing to complete. To avoid an
  indefinite wait, code has been added to read the status 
  incrementally from 100ms up to 1.5 seconds.

  This is a defect placeholder for submitting a patch to Canonical, that is in the process of getting submitted upstream for the 4.8 kernel.

  We would like to have this patch included in the pointrelease,

  Please lookout for the patch that will be attached to this bug soon
  and probably closer to the deadline for 16.04.1.

  I will submit the patch as soon as I get the review comments addressed
  and well tested.
