Hmm ... the patch still does not apply ... having closer look ....
It appears that you don't use the mainline kernel. Commit 8d008c0c
is not upstream. It is in a stable release. Only which one ... ok,
I see it in linux-4.9.y. The offending commit is also in 4.4.y,
4.14.y, and 4.15.y. The fix needs to be pulled from upstream into
those stable releases. I'll send a request to Greg.
Thanks,
Guenter
