There is now less need for the vfs.usermount sysctl. msdosfs already
has this change, modulo a missing LK_RETRY, via NetBSD. At least
ext2fs is missing this and many other changes from Lite2.

times consistently wrong (up to 1 tick too late), but recent changes
fixed the setting of the main clock, making other times inconsistent.
The inconsistencies tended to show up as a negative resource usage
for the process that set the time.
Fixed the check for setting the clock backwards. A stale timestamp
(`time') was checked, so it was possible to set the clock backwards
by up to almost 1 tick. Until recently, this bug was compensated
for by setting the clock consistently wrong.
Merged the comment about setting the clock backwards from Lite2.
Removed latency micro-optimizations/speed pessimizations in settime().
microtime() and set_timecounter() are relatively expensive, and
they must be called together with clock updates blocked to get a
consistent `delta', so significant latency optimizations are not
possible.
Removed some stale comments.
use the default without losing any (currently unused) features.
(CLEANDIRS is only used by for libgmp and libmp via bsd.lib.mk, and
only documented everywhere it is supported except of course where it
is actually used.)
sources can't include it. However, until recently it was included
by <sys/stat.h>, so it should have been (almost) entirely inside
_POSIX_SOURCE ifdefs for <sys/stat.h> to be (almost) POSIX.1 conformant,
but it was only about half inside _POSIX_SOURCE ifdefs.
longstanding namespace pollution. The need for the pollution
(unconditional use of timespecs) went away in the first round of
Lite2 merges (rev.1.7 for stat.h), but <sys.time.h> was still
unconditionally included, and a stale comment about the need for
the pollution was not removed.
improve tuning on larger systems. (A couple of the VM tuning params for
small systems were so badly chosen that the system could hang under load.)
The broken tuning was originaly my fault.
the main #include of it.
Fixed disordering of _BSD_CLOCKID_T.
Removed forward declarations of "common" structs. The declarations are
now made closer to where they are used.
specifies exiting with a zero status if the file was copied
successfully, and with a nonzero status if an error occurred. We
are too sloppy to tell if the file was copied successfully when we
get killed by a SIGINT, but it is unlikely to have been. Added a
comment about related sloppiness (calling exit() from a signal
handler).
