Subject: [PATCH v2 13/15] KVM: TDX: Rename tdx_sept_remove_private_spte() to show it's for leaf SPTEs
Date: Sat,  9 May 2026 15:57:19 +0800	[thread overview]
Message-ID: <20260509075719.4338-1-yan.y.zhao@intel.com> (raw)
In-Reply-To: <20260509075201.4077-1-yan.y.zhao@intel.com>

Rename tdx_sept_remove_private_spte() to tdx_sept_remove_leaf_spte() to
clearly show that this function is for removal of leaf SPTEs.

No functional change intended.
