This patch has problems.

kernel/cpuset.c: In function 'cpuset_write_resmask':
kernel/cpuset.c:1374: warning: passing argument 2 of 'update_nodemask' discards qualifiers from pointer target type

Did you not get this warning also?

I don't know how to fix it. cftype.write_string() requires a const
char* in the third arg, but we then go on to call update_nodemask(),
which does a strstrip() on this allegedly-const char array.

Taking a copy of the string in update_nodemask() would fix things, but
that's pretty lame.
