Subject: [PATCH v2 14/29] KVM: x86: hyper-v: Rename kvm_hv_vcpu_purge_flush_tlb()
Date: Thu, 8 Oct 2026 00:14:10 +0000 [thread overview]
Message-ID: <20261008001425.2458927-15-yosry@kernel.org> (raw)
In-Reply-To: <20261008001425.2458927-1-yosry@kernel.org>
Rename kvm_hv_vcpu_purge_flush_tlb() to kvm_hv_purge_tlb_flush_fifo() to
clarify that it purges the TLB flush FIFO, not purge *and* flush the
TLB.
No functional change intended.
