Subject: [PATCH 10/16] KVM: x86/mmu: Rename lpage_disallowed to account_disallowed_nx_lpage
Date: Fri,  6 Dec 2019 15:57:23 -0800	[thread overview]
Message-ID: <20191206235729.29263-11-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191206235729.29263-1-sean.j.christopherson@intel.com>

Rename __direct_map()'s param that controls whether or not a disallowed
NX large page should be accounted to match what it actually does.  The
nonpaging_page_fault() case unconditionally passes %false for the param
even though it locally sets lpage_disallowed.

No functional change intended.
