Subject: [PATCH 4/5] KVM: x86/mmu: Use innermost rmap zap helper when recycling rmaps
Date: Tue, 12 Jul 2022 01:55:57 +0000 [thread overview]
Message-ID: <20220712015558.1247978-5-seanjc@google.com> (raw)
In-Reply-To: <20220712015558.1247978-1-seanjc@google.com>
Use ____kvm_zap_rmaps() directly when recycling rmaps instead of bouncing
through kvm_zap_rmaps() and __kvm_zap_rmaps(). Calling kvm_zap_rmaps()
is unnecessary and odd as it requires passing dummy parameters; passing
NULL for @slot when __rmap_add() already has a valid slot is especially
weird and confusing.
No functional change intended.
