From: Liu, Yi L yi.l.liu@intel.com Sent: Thursday, February 8, 2024 4:23 PM

static void intel_nested_domain_free(struct iommu_domain *domain) {

• struct dmar_domain *dmar_domain = to_dmar_domain(domain);
• struct dmar_domain *s2_domain = dmar_domain->s2_domain;
• spin_lock(&s2_domain->s1_lock);
• list_del(&dmar_domain->s2_link);
• spin_unlock(&s2_domain->s1_lock); kfree(to_dmar_domain(domain));

use 'dmar_domain'.
