Comment 2 Michael Orlitzky gentoo-dev 2018-01-30 04:03:16 UTC 
I can't test it at the moment because my kernel situation is all screwed up, but I just added tp_smapi-0.42-r2 to the tree with the patch. Can you please make sure it works?
Comment 3 Jeremy Stent 2018-01-30 14:25:07 UTC 
This seems to work fine for kernel 4.15 and for an earlier kernel.  Thank you for your assistance.
