This patch does easy mistake, namely trivial switch from simple_strtoul() to
kstrtoul().
But you have to remember that there are NO simple_strtoint() or something like
that,
so real type of data is anchor not function name.
In the code above data are "sig" and "pid" which are "int" or "unsigned int" at
most.
Later "sig" is negated, so "int sig" is OK.
Pids are always unsigned logically so "unsigned int" is correct.
Don't be afraid to switch type of variable to correct one. Most of
the time "unsigned long foo" is wrong becase C-derived api didn't offer
anything better.
