The current text was confused (mea culpa). No signal is sent to
the init() process. Rather, depending on the 'cmd' given to
reboot(), the 'group_exit_code' value will set to either SIGHUP or
SIGINT, with the effect that one of those signals is reported to
wait() in the parent process.

hugetlbfs support for memfd_create() was recently merged by Linus

support a new memfd_create() flag (MFD_HUGETLB) was added.

mremap.2: Add description of old_size == 0 functionality
...
Since at least the 2.6 time frame, mremap() would create a new
mapping of the same pages if 'old_size == 0'. It would also leave
the original mapping. This was used to create a 'duplicate
mapping'.
A recent change was made to mremap() so that an attempt to create a
duplicate a private mapping will fail.
Document the 'old_size == 0' behavior and new return code from
below commit.

membarrier.2: Update example to take TSO into account
...
The existing example given specifically states that it focus on
x86 (TSO memory model), but gives a read-read vs write-write
ordering example, even though this scenario does not require
explicit barriers on TSO.
So either we change the example architecture to a weakly-ordered
architecture, or we change the example to a scenario requiring
barriers on x86.
Let's stay on x86, but provide a Dekker as example instead.

the AT_NO_AUTOMOUNT flag.
The text in the NOTES is removed and places with the text for
AT_NO_AUTOMOUNT to improve cohesion.

getrlimit.2, mmap.2, malloc.3: RLIMIT_DATA affects mmap (2) since Linux 4.7
...
Starting with Linux kernel 4.5 and 84638335900f1995
(mm: rework virtual memory accounting) RLIMIT_DATA affects
mmap(2). With d977d56ce5b3e88 (mm: warn about VmData over
RLIMIT_DATA) only warnings are emmitted when going over the
specified RLIMIT_DATA in 4.5.
As of 4.7 and f4fcd55841fc9 (mm: enable RLIMIT_DATA by default
with workaround for valgrind) going over RLIMIT_DATA through
mmap(2) is forbidden.

It would have been obvious that these limits are in bytes, except that
"ulimit -a" in at least bash, dash and zsh says that they're in blocks.
This confused me, so I had to check the kernel source code.
My understanding is that they are indeed in bytes, so mention this
information in the man page.

ioctl_tty.2: Add TIOCGPTPEER documentation
...
This is an ioctl(2) recently added by myself, to allow for
container runtimes and other programs that interact with
(potentially hostile) Linux namespaces to safely create
{master,slave} pseudoterminal pairs without needing to open
potentially unsafe /dev/pts/... filenames that may be malicious
mount points or similar in an untrusted namespace (avoiding the
endless issues with ptsname(3) and similar approaches).

getpid.2: Note that PID caching is removed as of glibc 2.25
...
Since glibc 2.25 the PID cache is removed.
Rationale given in the release notes:
https://sourceware.org/glibc/wiki/Release/2.25#pid_cache_removal
~~~
3.2.3. Calls to getpid are no longer cached
The PID cache used by glibc has been removed. In certain scenarios
the cache was not 100% reliable and because of that it was deemed
safer to remove the cache than to potentially return a wrong
answer.
Applications performing getpid() calls in a loop will see the
worst case performance degradation as the library call will
perform a system call at each invocation. Such application uses
were known to exist at least in OpenSSL (fork()-based PRNG
invalidation), but supporting the performance of that specific
invalidation mechanism was not judged to have sufficient value
against immediate and long-term benefits of removing the cache.
Functional reasons exist for the PID cache removal including
problems with PID namespaces, interoperability with raw system
calls (BZ#17214, Chrome: Issue 800183004), and improvements to
spawn (BZ#19957). Performance is actually increased in
pthread_create() with the removal of the cache since the
implementation no longer needs to perform an invalidation step.
Applications performing getpid() in a loop that need to do some
level of fork()-based invalidation can instead use
pthread_atfork() to register handlers to handle the invalidation.
There is work-in-progress to make pthread_atfork() available to
applications that do not link against libpthread.so (Provide
pthread_atfork() without libpthread.so).
Other kinds of invalidation are not supported and the glibc
community will actively look at a kernel assisted mechanism for
state management across fork(), vfork(), clone() and other
interfaces which can benefit from such semantics. It is the same
type of solution required for crypto PRNG reset across such API
calls.

seccomp(2): Expand SECCOMP_RET_KILL documentation
...
First clarify that the process cannot catch this SIGSYS signal.
While the text currently says that, it's easy (IMO) to read
ambiguously and that it's referring to default behavior (no
handler -> process exits).
Then add details regarding coredump behavior. Before Linux 4.11,
there was no way to get coredumps from such crashes. Now we can
at least get crashes from single threaded processes.
