Subject: [PATCH v6 01/38] KVM: x86: Rename 'enable_direct_tlbflush' to 'enable_l2_tlb_flush'
Date: Mon,  6 Jun 2022 10:36:18 +0200	[thread overview]
Message-ID: <20220606083655.2014609-2-vkuznets@redhat.com> (raw)
In-Reply-To: <20220606083655.2014609-1-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.
