definition files that are used only for extracting symbols. This is useful
for inter-module dependencies and files containing only enum-definitions.

current state, it can handle all but four of the 991 zip files (including
jar files) I was able to identify in the ports tree. The remaining four
are two self-extracting archives and two which have garbage preceding the
first local header. This limitation is a feature of libarchive(3) which
I am currently working to resolve.
The code is unnecessarily large due to the need to emulate the exact
command-line syntax and behaviour of ports/unzip. My initial incompatible
implementation was one quarter the size of the one I am committing here.
the rejected mail reports to tally the rejects per blacklist without
providing details about individual sender hosts. The default configuration
keeps the reports in their original form.

dev2udev() when a tty was being detached concurrently with the sysctl
handler:
- Hold the 'tty_list_mutex' lock while we read all the fields out of the
struct tty for copying out later. Previously the pty(4) and pts(4)
destroy routines could set t_dev to NULL, drop their reference on the
tty and destroy the cdev while the sysctl handler was attempting to
invoke dev2udev() on the cdev being destroyed. This happened when the
sysctl handler read the value of t_dev prior to it being set to NULL
either due to it being stale or due to timing races. By holding the
list lock we guarantee that the destroy routines will block in ttyrel()
in that case and not destroy the cdev until after we've copied all of our
data. We may see a NULL cdev pointer or we may see the previous value,
but the previous value will no longer point to a destroyed cdev if we
see it.
- Fix the ttyfree() routine used by tty device drivers in their detach
methods to use ttyrel() on the tty so we don't leak them. Also, fix it
to use the same order of operations as pty/pts destruction (set t_dev
NULL, ttyrel(), destroy_dev()) so it cooperates with the sysctl handler.

This makes it possible to support ftruncate() on non-vnode file types in
the future.
- 'struct fileops' grows a 'fo_truncate' method to handle an ftruncate() on
a given file descriptor.
- ftruncate() moves to kern/sys_generic.c and now just fetches a file
object and invokes fo_truncate().
- The vnode-specific portions of ftruncate() move to vn_truncate() in
vfs_vnops.c which implements fo_truncate() for vnode file types.
- Non-vnode file types return EINVAL in their fo_truncate() method.

add correct locking to the operation of unmounting.
This will prevent debugging kernels from panicking if mounting a
non-hpfs partition (I'm not sure if this can be a problem with a
successful mounting operation though).

CVSROOT/config file options that control keyword expansion. cvs-1.12 has
its own $Id$ expansion controls and they're configured in CVSROOT/config
rather than CVSROOT/options. The problem is that current cvs-1.11.x
doesn't understand the future keywords.....
Add trivial forward support for the new keywords for when cvs-1.12
hits the tree down the road. CVSROOT/options won't be going away - cvsup
uses it.
pv_list_count from struct md_page. Ever since Peter rewrote the pv
entry allocator for amd64 and i386 pv_list_count has been correctly
maintained but otherwise unused.
- spell 16384 as 16384 and not as BKVASIZE. 16384 is (not quite) just a
magic size that works well in practice. BKVASIZE should be MAXBSIZE
(65536), but is 16384 because i386's don't have enough kva for it to
be MAXBSIZE; 16384 works (not so well) for it for much the same reasons
that it works well in the heuristic.
- expand and/or add comments about this and other details.
- don't explicitly inline this function.
- fix some other style bugs.
ABI override binary isn't found. This could probably be smoother, but
it is what I did in p4 change #126891 on 2007/09/27. It should solve

default. This has the disadvantage of rendering the datasize resource
limit irrelevant, but without this change, legitimate uses of more
memory than will fit in the data segment are thwarted by default.
Fix chunk_alloc_mmap() to work correctly if initial mapping is not
chunk-aligned and mapping extension fails.
the number of bytes read is actually not important as long as we have at
least what we ask for. Illustrate its benefits by using it throughout
the ZIP support code, except for the few cases where it doesn't apply.

allocation, free the indirect blocks before clearing the disk pointers,
that could lead to the softupdate inconsistencies in the case of the
machine or disk crash at the wrong time.
Rearrange the recover code to do the ffs_blkfree() after the second
ffs_syncvnode(), that clears the pointers chain.
