queue items that can be allocated by netgraph and the number of free queue
items that are cached on a private list.
Netgraph places an upper limit on the number of queue items it may allocate.
When there is a large number of netgraph messages travelling through the
system (100k/sec and more) there is a high probability, that messages get
queued at the nodes and netgraph runs out of queue items. In this case the data
flow through netgraph gets blocked. The tuneable for the number of free
items lets one trade memory for performance.
The tunables are also available as read-only sysctls.

Both "product" and "build" ordering are rampant in /usr/src. This document
is not indented to be as strict as style(9) as historically BSD hasn't been
as consistent about Makefile as C code. Also there are too many variations,
exceptions and allowances in out existing Makefile style to be strict.
However there is a general level of consensus on what the general BSD style
of our Makefiles is. This manpage documents that "smell".
o Give the proper spelling for WARNS.
o Clarify using NO_WERROR.
o Embelish -D after -I verbage.
o Document preference of ${.ALLSRC} & ${.TARGET} vs. $< & $@.

program allows users in the operator group to take filesystem
snapshots. Its first use will be in support of `dump -L'.

are specified the old behaviour is old. The submitted applied a much cleaner
diff to ruptime.c, however it did not cover cases like listing failures. It
would probably be a good idea to move the printing from the ruptime function,
and have that function just be used to build the list, as that would unbreak
sorting, but this diff is intended to be clear, relative to the original
code. As the sort order is the order specified on the command line, for now,
such is documented in the manual page accordingly.
