Subject: [PATCH v2 20/21] KVM: MIPS: Account pages used for GPA page tables
Date: Mon, 22 Jun 2020 13:08:21 -0700 [thread overview]
Message-ID: <20200622200822.4426-21-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200622200822.4426-1-sean.j.christopherson@intel.com>
Use GFP_KERNEL_ACCOUNT instead of GFP_KERNEL when allocating pages for
the the GPA page tables. The primary motivation for accounting the
allocations is to align with the common KVM memory cache helpers in
preparation for moving to the common implementation in a future patch.
The actual accounting is a bonus side effect.
