Cover letter [PATCH v6 0/3] vfio-ccw: Fix interrupt handling for HALT/CLEAR

Hi Conny, Matt, Halil,

Here's one (last?) update to my proposal for handling the collision between interrupts for START SUBCHANNEL and HALT/CLEAR SUBCHANNEL.

Only change here is to include Conny's suggestions on patch 3.

Thanks,
Eric
