prctl.2: Correct some details for PR_SET_TIMERSLACK
...
In kernel/sys.c, arg2 is an unsigned long value and it will never
less than 0. Also, since kernel commit id da8b44d5a9f8 (Linux
4.6), timer_slack_ns and default timer_slack_ns have been
converted into u64, the return value of PR_GET_TIMERSLACK has been
limited under ULONG_MAX.
The timer slack value also can be inherited by a child created via
fork(2).

prctl.2: Explain the circumstances in which the parent-death signal is sent
...
To test the behavior documented by this patch, the following
demos employ the program shown at the foot of this commit message.
First, show that the pdeath signal is sent when the parent
terminates:
$ ./pdeath_signal 0 10 4
Parent (18595) about to sleep for 4 seconds
Child about to set PR_SET_PDEATHSIG
Child about to sleep
Parent (18595) terminating
*********** Child (18596) got signal; si_pid = 18595; si_uid = 1000
Parent PID is now 1403
$ Child about to exit
But the signal is not sent if the parent terminates before the
child uses PR_SET_PDEATHSIG:
$ ./pdeath_signal 2 10 0
Parent (18707) about to sleep for 0 seconds
Parent (18707) terminating
Child about to sleep 2 seconds before setting PR_SET_PDEATHSIG
$ Child about to set PR_SET_PDEATHSIG
Child about to sleep
Child about to exit
Demonstrate that the pdeath signal is sent on termination of each
ancestor subreaper process:
$ ./pdeath_signal 2 10 3 7 6 5
18786 marked itself as a subreaper
18786 subreaper about to sleep 7 seconds
18787 marked itself as a subreaper
18787 subreaper about to sleep 6 seconds
18788 marked itself as a subreaper
18788 subreaper about to sleep 5 seconds
Parent (18789) about to sleep for 3 seconds
Child about to sleep 2 seconds before setting PR_SET_PDEATHSIG
Child about to set PR_SET_PDEATHSIG
Child about to sleep
Parent (18789) terminating
*********** Child (18790) got signal; si_pid = 18789; si_uid = 1000
Parent PID is now 18788
18788 subreaper about to terminate
*********** Child (18790) got signal; si_pid = 18788; si_uid = 1000
Parent PID is now 18787
18787 subreaper about to terminate
*********** Child (18790) got signal; si_pid = 18787; si_uid = 1000
Parent PID is now 18786
18786 subreaper about to terminate
*********** Child (18790) got signal; si_pid = 18786; si_uid = 1000
Parent PID is now 1403
$ Child about to exit
But in the case where some subreapers terminate before they
have a chance to adopt the child, the terminations of those
subreapers do not result in a signal for the child:
$ ./pdeath_signal 2 10 3 5 6 7
18836 marked itself as a subreaper
18836 subreaper about to sleep 5 seconds
18837 marked itself as a subreaper
18837 subreaper about to sleep 6 seconds
18838 marked itself as a subreaper
18838 subreaper about to sleep 7 seconds
Parent (18839) about to sleep for 3 seconds
Child about to sleep 2 seconds before setting PR_SET_PDEATHSIG
Child about to set PR_SET_PDEATHSIG
Child about to sleep
Parent (18839) terminating
*********** Child (18840) got signal; si_pid = 18839; si_uid = 1000
Parent PID is now 18838
18836 subreaper about to terminate
$ 18837 subreaper about to terminate
18838 subreaper about to terminate
*********** Child (18840) got signal; si_pid = 18838; si_uid = 1000
Parent PID is now 1403

prctl.2: Defer to capabilities(7) for discussion of the "keep capabilities" flag
...
It makes no sense to describe this flag in two different
manual pages, so consolidate the description to one page.
Furthermore, the following statement that was in the prctl(2)
page is not correct:
A thread's effective capability set is always cleared
when such a credential change is made, regardless of
the setting of the "keep capabilities" flag.
The effective set is not cleared if, for example, the
credential sets were [ruid != 0, euid != 0, suid == 0]
and suid is switched to zero while the "keep capabilities"
flag is set.

prctl.2, hier.7: spfix: sharable-->shareable
...
Even in American English, it seems that "shareable"
is the more common form these days.
