man/man2/openat2.2: HISTORY: Include epilogue about FreeBSD

While RESOLVE_BENEATH was based on FreeBSD's O_BENEATH, there was a
well-known safety issue in O_BENEATH that we explicitly avoided
replicating -- FreeBSD would only verify whether the lookup escaped the
dirfd *at the end of the path lookup*.

This meant that even with O_BENEATH, an attacker could gain information
about the structure of the filesystem outside of the dirfd through
timing attacks or other side-channels.

Once Linux had RESOLVE_BENEATH, FreeBSD implemented O_RESOLVE_BENEATH to
mimic the same behaviour[1] and eventually removed O_BENEATH entirely
from their system[2].  It seems prudent to provide this epilogue in the
HISTORY section of the openat2(2) man page (the FreeBSD man page does
for open(2) not reference this historical connection with Linux at all,
as far as I can tell).

man/man2/statx.2: Add stx_atomic_write_unit_max_opt

XFS supports atomic writes - or untorn writes - based on two different
methods:
- HW offload in the disk
- FS method based on out-of-place writes

The value reported in stx_atomic_write_unit_max will be the max size of the
FS-based method.

The max atomic write unit size of the FS-based atomic writes will
typically be much larger than what is capable from the HW offload. However,
FS-based atomic writes will also be typically much slower.

Advertise this HW offload size limit to the user in a new statx member,
stx_atomic_write_unit_max_opt.

We want STATX_WRITE_ATOMIC to get this new member in addition to the
already-existing members, so mention that a value of 0 in
stx_atomic_write_unit_max_opt means that stx_atomic_write_unit_max holds
this optimised limit.

Linux will zero unused statx members, so stx_atomic_write_unit_max_opt
will always hold 0 for older kernel versions which do not support
this FS-based atomic write method (for XFS).

It suggest 'cancellation' instead of 'cancelation', but we want the
latter.  Since it hasn't caught anything useful, AFAIR, turn it off.

man/man2/open.2: Fix doc for O_CREAT | O_DIRECTORY

Although Linux kernels before 5.7 would create a regular file when
opening a nonexistent file with O_CREAT | O_DIRECTORY, this behavior
was changed to something deeply buggy in 5.7, and when the bug was
fixed in 6.4 this combination of open flags became invalid.

Adjust the documentation to match the 6.4+ behavior,
which makes more sense anyway.
