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 Previous versions: v5: https://lore.kernel.org/kvm/20210510205646.1845844-1-farman@xxxxxxxxxxxxx/ v4: https://lore.kernel.org/kvm/20210413182410.1396170-1-farman@xxxxxxxxxxxxx/ v3: https://lore.kernel.org/kvm/20200616195053.99253-1-farman@xxxxxxxxxxxxx/ v2: https://lore.kernel.org/kvm/20200513142934.28788-1-farman@xxxxxxxxxxxxx/ v1: https://lore.kernel.org/kvm/20200124145455.51181-1-farman@xxxxxxxxxxxxx/ Eric Farman (3): vfio-ccw: Check initialized flag in cp_init() vfio-ccw: Reset FSM state to IDLE inside FSM vfio-ccw: Serialize FSM IDLE state with I/O completion drivers/s390/cio/vfio_ccw_cp.c | 4 ++++ drivers/s390/cio/vfio_ccw_drv.c | 12 ++++++++++-- drivers/s390/cio/vfio_ccw_fsm.c | 1 + drivers/s390/cio/vfio_ccw_ops.c | 2 -- 4 files changed, 15 insertions(+), 4 deletions(-) -- 2.25.1
