Subject: [PATCH v3 0/5] KVM: s390: A few misc gmap fixes.
Date: Thu, 11 Jun 2026 12:48:45 +0200	[thread overview]
Message-ID: <20260611104850.110313-1-imbrenda@linux.ibm.com> (raw)

A few more minor gmap fixes.

v2->v3:
* Fix allocation size of struct vsie_rmap in kvm_s390_mmu_cache_topup()
* Account for the possible failure of radix_tree_preload()
* Move kvm_s390_mmu_cache_topup() inside the retry loop in
  _gaccess_shadow_fault(), to guarantee forward progress

v1->v2:
* Improve suppression of __must_check, by using a pointless if instead
  of casting to (void)
* Fix allocation size for struct vsie_rmap in kvm_s390_mmu_cache_topup()
* Add missing radix_tree_preload() in _gaccess_shadow_fault()
