Subject: [PATCH v3 01/20] intel_iommu: Rename vtd_ce_get_rid2pasid_entry to vtd_ce_get_pasid_entry
Date: Tue,  8 Jul 2025 07:05:42 -0400	[thread overview]
Message-ID: <20250708110601.633308-2-zhenzhong.duan@intel.com> (raw)
In-Reply-To: <20250708110601.633308-1-zhenzhong.duan@intel.com>

In early days vtd_ce_get_rid2pasid_entry() was used to get pasid entry
of rid2pasid, then it was extended to get any pasid entry. So a new name
vtd_ce_get_pasid_entry is better to match what it actually does.

No functional change intended.
