New Revision: 204413
URL: http://svn.freebsd.org/changeset/base/204413
Log:
For kinfo_proc in kp->ki_siglist, return the set of the signals pending
in the process queue when gathering information for the process, and set
of signals pending for the thread, when gathering information for the
thread. Previously, the sysctl returned a union of the process and some
arbitrary thread pending set for the process, and union of the process
and the thread pending set for the thread.
