Subject: [PATCH v3 03/12] KVM: x86/mmu: rename try_async_pf to kvm_faultin_pfn
Date: Mon,  2 Aug 2021 21:33:20 +0300	[thread overview]
Message-ID: <20210802183329.2309921-4-mlevitsk@redhat.com> (raw)
In-Reply-To: <20210802183329.2309921-1-mlevitsk@redhat.com>

try_async_pf is a wrong name for this function, since this code
is used when asynchronous page fault is not enabled as well.

This code is based on a patch from Sean Christopherson:
https://lkml.org/lkml/2021/7/19/2970

Suggested-by: Sean Christopherson <seanjc@google.com>
Signed-off-by: Maxim Levitsky <mlevitsk@redhat.com>
