Returning a status response code 06 (Invalid address of AP-queue notification byte) when the call to register a guest ISC fails makes no sense. 2. The pages containing the interrupt notification-indicator byte are not freed after a failure to register the guest ISC fails. Anthony Krowiak (2): s390/vfio-ap: unpin pages on gisc registration failure s390/vfio-ap: set status response code to 06 on gisc registration failure Tony Krowiak (1): s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command drivers/s390/crypto/vfio_ap_ops.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-)
