This feature provides a deterministic hot plugging semantics of AP queues that may be bound to multiple drivers. In particular it enables to configure an AP queue (APQN) as being bound to a particular driver even if the associate HW gets intermittently lost and reconnected. s390-tools part. Backport from 2.7.0 to 2.6.0 Git commit: for s390-tools 2.7.0 https://github.com/ibm-s390-tools/s390-tools/commit/0a0b4c382693cded5652404e8fa2c0e483aa33df lszcrypt: support for alternate zcrypt device drivers It needs to be applied to 2.6.0 for Ubuntu 18.10, which will apply seamlessly
