- 'mv longnamedfile1 longnamedfile2' would cause longnamedfile2 to lose its
long name.
- Long names have trailing spaces/dots stripped for lookup as well as
assignment.
- A lockup when the mdsosfs was accessed from within the Linux emulator is fixed.
- A bug whereby long filenames were recognised by Microsoft operating systems but
not FreeBSD is fixed.

These diffs implement the first stage of a VOP_{GET|PUT}PAGES pushdown
for local media FS's.
See ffs_putpages in /sys/ufs/ufs/ufs_readwrite.c for implementation
details for generic *_{get|put}pages for local media FS's. Support
is trivial to add for any FS that formerly relied on the default
behaviour of the vnode_pager in in EOPNOTSUPP cases (just copy the
ffs_getpages() code for the FS in question's *_{get|put}pages).
Obviously, it would be better if each local media FS implemented a
more optimal method, instead of calling an exported interface from
the /sys/vm/vnode_pager.c, but this is a necessary first step in
getting the FS's to a point where they can be supplied with better
implementations on a case-by-case basis.
Obviously, the cd9660_putpages() can be rather trivial (since it
is a read-only FS type 8-)).
A slight (temporary) modification is made to print a diagnostic message
in the case where the underlying filesystem attempts to engage in the
previous behaviour. Failure is likely to be ungraceful.

Fixed pedantic semantics errors (in ANSI C, static arrays must have
a size, and static objects should be consistently declared as static
unless you know more than anyone should have to know about the
linkage rules).
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.
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.
have declined due to code-rot over time. The swap pager rundown code
has been clean-up, and unneeded wakeups removed. Lots of splbio's
are changed to splvm's. Also, set the dynamic tunables for the
pageout daemon to be more sane for larger systems (thereby decreasing
the daemon overheadla.)
in a way identically as before.) I had problems with the system properly
handling the number of vnodes when there is alot of system memory, and the
default VM_KMEM_SIZE. Two new options "VM_KMEM_SIZE_SCALE" and
"VM_KMEM_SIZE_MAX" have been added to support better auto-sizing for systems
with greater than 128MB.
Add some accouting for vm_zone memory allocations, and provide properly
for vm_zone allocations out of the kmem_map. Also move the vm_zone
allocation stats to the VM OID tree from the KERN OID tree.
