Modified Files:
src/sys/kern: kern_sig.c
Log Message:
Fix sigactsunshare() to do what the manpage and the commit tells it to do!
I.e. unshare a process its sigacts by creating a new one BUT maintaining all
signal state.
The old code would CLEAR all the signal state. It used to work only due to the
fact that sigactunshare() is only used in execsigs() and the fact that
SIG_DFL was NULL.
