Re: [PATCH] drm/amdkfd: bump KFD version for unified ctx save/restore memory

[Felix Kuehling <felix.kuehling@amd.com>]

Eric sent out the corresponding user mode patches to the mailing list as 
well. It looks a bit weird, because it looks like they're part of the 
same patch series. But patch 2 and 3 are actually user mode patches. The 
interesting one is patch 3.


Do we still need a link to a user mode patch in this case?


Regards,
   Felix
