[PATCH v2 0/7] KVM: s390: Misc fixes

Posted by Claudio Imbrenda 1 week, 5 days ago

Fix a bunch of small issues that came up during the previous round of fixes.

They are mostly extremely unlikely races, but they should be fixed
nonetheless.

v1->v2
* Drop some patches that have been picked upstream in the meantime.
* Drop patch 3, as it was trying to fix a bug that does not exist
* Avoid the NULL gmap dereference by using a flag
* Fix the return value of kvm_s390_[gp]et_skeys too
* Use kvm->slots_arch_lock instead of kvm->slots_lock for CMMA and ESSA
  handling, to avoid potential deadlocks with the RCU.
* Three new patches to fix other issues that came out while fixing the
  other issues
