Sorry, I don't know where to get a series file for this patchset?

It sounds like your tree doesn't #include <linux/sched.h> at the top of
include/linux/nsproxy.h.  That was added by a separate patch I think
last week - a few architectures (which i was testing) had a #include chain
which ended up in sched.h being included free, but some arches had a
different chain.

Anyway please try #include <linux/sched.h> at the top of
include/linux/nsproxy.h and let me know if that doesn't fix the problem.

thanks,
