If a buffer is never bound to a virtual memory pagetable than don't try to unbind it. Only drawback is that we don't update the pagetable when unbinding the ib pool buffer which is fine because it only happens at suspend or module unload/shutdown. Fixes spurious messages about buffers without VM mappings. E.g.: radeon 0000:01:00.0: bo ffff88020afac400 don't has a mapping in vm ffff88021ca2b900 Cc: stable@kernel.org Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
