From 6419bc52072b928acb764766968c672d5fede802 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 10 Oct 2024 11:23:13 -0700 Subject: KVM: Rename gfn_to_page_many_atomic() to kvm_prefetch_pages() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rename gfn_to_page_many_atomic() to kvm_prefetch_pages() to try and communicate its true purpose, as the "atomic" aspect is essentially a side effect of the fact that x86 uses the API while holding mmu_lock. E.g. even if mmu_lock weren't held, KVM wouldn't want to fault-in pages, as the goal is to opportunistically grab surrounding pages that have already been accessed and/or dirtied by the host, and to do so quickly.
