I think you are not getting my point. struct amdgpu_task_info has 3 more 
parameters: process_name, task_name and tgid.

When VRAM is not lost: we are getting the whole new amdgpu_task_info 
structure, and all parameters are valid.

When VRAM is lost: we should reset all parameters of amdgpu_task_info 
structure, not just pid. Else other params may contain garbage.

So what I mean is:
instead of
tmp_adev->reset_context_task_info.pid = 0;

do something like:
memset(&tmp_adev->reset_context_task_info.pid, 0, 
sizeof(reset_context_task_info));
