>Description:

The kill(2) manual page for CURRENT states "A single exception is the
signal SIGCONT, which may always be sent to any descendent of the current
process."

In CURRENT, however, this provision is false:  the process can send
SIGCONT to any other process in the caller's session (to align with POSIX).

Behavior has been tested, also reference:
p_cansignal() function in /sys/kern/kern_prot.c

>How-To-Repeat:

man 2 kill

>Fix:

Change sentence in question to:

	"A single exception is the signal SIGCONT, which may always be sent
	to any process with the same session ID as the caller."

or something similar.
