Did you get this?

kernel/sched/core.c: In function 'sched_setaffinity':
kernel/sched/core.c:4333: error: implicit declaration of function 'task_ns_capable'

Apparently because Eric has today added a two-month old patch into
linux-next at the same time as mainline moved the entire file.

Eric, please never put 3.x material into linux-next until 3.x-rc1 has
opened.  Please remove these patches from linux-next until 3.3-rc1
opens.


Also, more gregmess:

And below is what I had to do to fix up all the conflicts between
mainline and linux-next.  This all results from a single morning's
merging into mainline.  It's mainly tools/perf.  I have to fix up
all this crap so I can get code tested and released.  Or I can turn
off the machines, stomp home and see if things have improved on
Monday.  Bye.
