KVM: selftests: Drop "vaddr_" from APIs that allocate memory for a given VM 2026-04-20T21:54:17+00:00 Sean Christopherson seanjc@google.com 2026-04-20T21:19:56+00:00 85819fa0e3b98682b8c57c6d8ba57e7a9c6032ea Now that KVM selftests use gva_t instead of vm_vaddr_t, drop "vaddr_" from the core memory allocation APIs as the information is extraneous and does more harm than good. E.g. the APIs don't _just_ allocate virtual memory, they allocate backing physical memory and install mappings in the guest page tables. And as proven by kmalloc() and malloc(), developers generally expect that allocations come with a working virtual address. Opportunistically clean up the function comment for vm_alloc(), and drop the misleading and superfluous comments for its wrappers. No functional change intended.
