no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

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

Otherwise, an additional blank line is inserted.

Include <machine/ansi.h> so that this file is self-sufficient again.

Cleaned up includes.
This man page may be overdoing the cross references by referencing

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

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
