H A D | kfd_events.c | 9b56bb11 Fri Oct 27 18:35:19 CDT 2017 Felix Kuehling <Felix.Kuehling@amd.com> drm/amdkfd: Don't dereference kfd_process.mm
The kfd_process doesn't own a reference to the mm_struct, so it can disappear without warning even while the kfd_process still exists.
Therefore, avoid dereferencing the kfd_process.mm pointer and make it opaque. Use get_task_mm to get a temporary reference to the mm when it's needed.
v2: removed unnecessary WARN_ON
