Modified Files:
src/sys/kern: sys_ptrace_common.c
Log Message:
PR/58896: Martin Husemann: PT_KILL will not deliver a kill signal to a stopped
process: When the process is stopped, the code resumes it instead of sending
the signal. Change it so that if we are sending SIGKILL, resume and send
the signal.
