Subject: [PATCH v6 0/3] vfio-ccw: Fix interrupt handling for HALT/CLEAR
Date: Tue, 11 May 2021 21:56:28 +0200	[thread overview]
Message-ID: <20210511195631.3995081-1-farman@linux.ibm.com> (raw)

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

Changelog:
v5->v6:
 - Add a block comment and rename variable in patch 3 [CH]
 - Drop RFC tag [EF]

v4->v5:
 - Applied Conny's r-b to patches 1 and 3
 - Dropped patch 2 and 4
 - Use a "finished" flag in the interrupt completion path
