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.

...
Based on a patch by Bjarni Ingi Gislason.
According to SI, ""The numerical value always precedes the unit,
and a space is always used to separate the unit from the number
[...] The only exceptions to this rule are for the unit symbols
for degree, minute, and second for plane angle."

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).

An off-by-one error could trigger a buffer overflow in

See https://bugzilla.kernel.org/show_bug.cgi?id=196483
Also some other cosmetic changes to the code (more comments,
better variable names).

umount.2: Revise MNT_FORCE description

MNT_FORCE does not allow a busy filesystem to be unmounted. Only
MNT_DETACH allows that. MNT_FORCE only tries to abort pending
transactions, in the hope that might help umount not to block,
Also, other filesystems than NFS support MNT_FORCE.

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.
