Message-ID: <1270644409-10123-6-git-send-email-joerg.roedel@amd.com> Date: Wed, 7 Apr 2010 14:46:42 +0200 From: Joerg Roedel <joerg.roedel@....com> To: Ingo Molnar <mingo@...hat.com> CC: x86@...nel.org, iommu@...ts.linux-foundation.org, linux-kernel@...r.kernel.org, Joerg Roedel <joerg.roedel@....com>, stable@...nel.org Subject: [PATCH 05/12] x86/amd-iommu: Use helper function to destroy domain In the amd_iommu_domain_destroy the protection_domain_free function is partly reimplemented. The 'partly' is the bug here because the domain is not deleted from the domain list. This results in use-after-free errors and data-corruption. Fix it by just using protection_domain_free instead.
