the size in the archive_entry object to zero if that format doesn't
store a body for that file type. This allows the client to determine
whether or not it should feed the file body to the archive. In
particular, cpio stores the file body for hardlinks, tar and shar
don't. With this change, bsdtar now correctly archives hardlinks in all
supported formats.
While I'm here, make shar output be more aggressive about creating directories.
Before this, commands such as:
bsdtar -cv -F shar some/explicit/path/to/a/file
wouldn't create the directory. Some simple logic to remember the last
directory creation helps reduce unnecessary mkdirs here.
At this point, I think the only flaw in libarchive's cpio support is
the failure to recognize hardlinks when reading.
While I'm here, fix a bug in reading filenames from
cpio files. (Copy should count the length of the name,
not the number of bytes available for input.)

lock already held rather than unlocking it only to turn around and
relock it.

because different resource limits are appropriate for transient and
"permanent" page wiring requests.
Retain the kern_mlock() and kern_munlock() API in the revived
vslock() and vsunlock() functions.
Combine the best parts of each of the original sets of implementations
with further code cleanup. Make the mclock() and vslock()
implementations as similar as possible.
Retain the RLIMIT_MEMLOCK check in mlock(). Move the most strigent
test, which can return EAGAIN, last so that requests that have no
hope of ever being satisfied will not be retried unnecessarily.
Disable the test that can return EAGAIN in the vslock() implementation
because it will cause the sysctl code to wedge.

The previous logic meant that if a user sets it to a minimal cooling value
acpi_thermal will not use higher cooling levels. Reverse the logic so that
the user requesting a level (say, 2) also gets 0 - 1 also.

DIAGNOSTIC instead of INVARIANTS. INVARIANTS is intended for tests
that don't substantially change code flow or behavior (passive), but
this test required locking both the proc lock and scheduler lock
in order to execute. It also appears to be a very advisory diagnostic
as opposed to an invariant violation.

- completely unused things
- all of rev.1.102 (C++ support). <sys/cdefs.h> is included by the
prerequisite <sys/types.h>. __BEGIN_DECLS/__END_DECLS has no effect
(except possibly if undefined behaviour is invoked using a hack like
defining away __inline) since this header doesn't really support any
extern functions.
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).
There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.
Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

included a start_precmd check for gated. The precommand was not
executed in the FreeBSD branch. When I did a mass removal of
NetBSD specific logic a while back this file apparently got only
a partial treatement. This bug did not have any functional consequences,
however, since the precommand was not declared to the rc.subr routines.
