Subject: [PATCH v7 01/39] KVM: x86: Rename 'enable_direct_tlbflush' to 'enable_l2_tlb_flush'
Date: Mon, 13 Jun 2022 15:38:44 +0200 [thread overview]
Message-ID: <20220613133922.2875594-2-vkuznets@redhat.com> (raw)
In-Reply-To: <20220613133922.2875594-1-vkuznets@redhat.com>
To make terminology between Hyper-V-on-KVM and KVM-on-Hyper-V consistent,
rename 'enable_direct_tlbflush' to 'enable_l2_tlb_flush'. The change
eliminates the use of confusing 'direct' and adds the missing underscore.
No functional change.
