BSD's who made this change quite some time ago. More commits to come.
and is module aware. Yes, this means that kvm_nlist(3) will find symbols
in loaded modules. The emulation of the nlist struct is pretty crude but
seems to work well enough for all the users in the tree that I found.
This fixes some nasty procfs problems for SMP, makes ps(1) run much faster,
and makes ps(1) even less dependent on /proc which will aid chroot and
jails alike.
To disable this facility and revert to previous behaviour:
sysctl -w kern.ps_arg_cache_limit=0

This cleanup was motivated by recent breakage of the default swap file

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Include <machine/ansi.h> so that this file is self-sufficient again.
Rev.1.6 doesn't do this as claimed unless <nlist.h> has nonstandard
pollution.
Cleaned up includes.
This man page may be overdoing the cross references by referencing

kvm_uread() is still completely undocumented in kvm*.3.
<kvm.h> is self-sufficient again.
Moved typedefs and forward struct declarations out of __BEGIN_DECLS/

Don't comment out the prototype for kvm_uread(). This was a 4 year
old kludge for previous breakage of self-sufficiency. The prototypwe
was broken instead.
Fixed bitrot (const poisoning) in the type of kvm_uread().
Fixed order of the declaration of kvm_uread().
fixes a type mismatch in the call to kvm_uread(). The bug has gone
undetected for almost 3 years because kvm_uproc()'s protoype has been
disabled for almost 4 years.
Trust sysctlbyname() to work properly if it succeeds.
Fixed style bugs in revs. 1.19 and 1.22.

In some cases replace if (a == null) a = malloc(x); else a =
realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is
guaranteed to be the same thing.
I've been running these on my system here w/o ill effects for some
time. However, the CTM-express is at part 6 of 34 for the CAM
changes, so I've not been able to do a build world with the CAM in the
