Subject: [PATCH 4.4 43/88] KVM: nVMX: Eliminate vmcs02 pool
Date: Fri, 14 Dec 2018 13:00:17 +0100 [thread overview]
Message-ID: <20181214115705.734729843@linuxfoundation.org> (raw)
In-Reply-To: <20181214115702.151309521@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jim Mattson <jmattson@google.com>
commit de3a0021a60635de96aa92713c1a31a96747d72c upstream.
The potential performance advantages of a vmcs02 pool have never been
realized. To simplify the code, eliminate the pool. Instead, a single
vmcs02 is allocated per VCPU when the VCPU enters VMX operation.
