lose the `buf' field instead of making a mess with it. Terminals with
fewer than 24 rows have never been supported.
The problem is not avoided by using curses since we use the last line

Move the non-vmstat fields {des,num,fre}vn from the vmstat display to a
new vnstat display. Move the dtbuf field there too. The buf and dtbuf
fields are non-vmstat and non-vnstat, so there is no good place to
display them. I need to move at least 1 of them out of the vm stats
for further cleanups of the vm stats, and there is only space for 1
of them in the vn stats. (The best place for the current buf field
is actually /dev/null, since it has been completely broken for about
10 years and broken for longer. It gives an uninteresting virtual
memory count where an interesting real memory count is wanted.)
to handle changes to the set of disks selected, but it is unnecessary
for that since the whole screen is redrawn when this set is changed.
It was also buggy:
- MAXDRIVES*6 = 42 was hard-coded as only 30 spaces in a string literal,
the last 2 disk names were not cleared as intended
- when the extended vmstats are active, clearing of even 30 columns
overruns the ozfod value field by 3 columns. This was harmless because
the field is much wider than necessary.
value printed is actually the optimized (i.e., the non-slow, not-on-the-fly
zero fills percentage) except in overflow cases. Describe it as %ozfod
in the display. Move the field descriptor 1 to the left so that there
is space for 5 characters after the % sign (this leaves no space between
the number and the descriptor but the % character serves well as a
separator).
Fixed integer overflow at z.ozfod = UINT_MAX/100 in the calculation of
%ozfod. This value can be reached just a few hours or minutes after
booting, so %ozfod was usually garbage in boot mode. Now %ozfod is
correct in boot mode for a few days or hours.
Print a non-dummy %ozfod when the division for it isn't division by 0
instead of when the result will be less than 100%. A result of 100%
may be correct, though a result of more than 100% indicates overflow
of one or both counters.

Move the load average up by 2 so that it starts in row 0 for all windows

Move everything below it up by 2 or 3 (3 for icmp and icmp6 which had

Notes by the submitter:
%%%
1. All the subwin() calls are identical using #define MAINWIN_ROW 3
(systat.h).
2. The load average is at the top of the window.
3. Each display starts on the fourth line. I made changes to those
displays that shifted the start line (i.e., icmp). This entailed a
lot of changes within the comments at the top of those displays.
4. For ip6, I shifted the "Input next-header histogram" column down one
row to separate it from "IPv6 Output". I raised "bad scope packets"
and "address selection failed" up one row to stay with "IPv6 Input"
(valid?). They were down one row to probably line up at the bottom,
but I think they should stick with their fellow items in a column.
5. I condensed ifstat a bit. It had a lot of empty rows.

only affect amd64 and i386. alpha uses "intr N" instead of "irqN" and
mostly has no device names. ia64 uses only device names.
- Edit interrupt names once after they are read from the kernel and not
every time they are displayed.
- Discard bogus trailing spaces so that the next step doesn't move things
to oblivion.
- If an interrupt name starts with "irqN:" (as it usually does in on
amd64 and i386), then move "irqN" to the end and strip ":", since we
have no space for the ":" and don't want to start descriptions with
"N" after stripping "irq" in the next step (since "N" would look like
a count). This step may need reworking for interrupt names containing
several device names -- then moving the irq number to the end would
lose it instead of losing some device names.
- Remove "irq" from an interrupt name if and only if the original name is
too long to display.
accidentally.
Read buffer overruns:
The size of the target array (TSOTTA == 10) is a wrong limit to use for
scanning the source string.
Write buffer overruns:
TSOTTA is also a wrong limit to use for copying to the target buffer,
since we want to add a NUL terminator afterwards. TSOTTA was also 1
too small for holding both the desired number of visible characters
and the NUL.
Worked accidentally:
There is error in the algorithm that tends to result in the space saved
by stripping "irq" not actually being used, but some cases worked
accidentally provided "irqN" is near the end of the source string and
"N" is only 1 digit.
Starting with 5.mumble-CURRENT, "irqN" is at the beginning of the
string on all (?) arches that have it and the accidents don't happen.
E.g. on i386's, the keyboard irq is now named
"irq1: atkbd0<bogus blank padding>" by the kernel, and this name was
converted to "1: atkb" -- not only the device number but part of the
device name has been lost --, while before 5.mumble the kernel name
was "atkbd0 irq1" and systat accidentally preserved the irq number to
give "atkbd0 1". The ":" in the string wastes precious space, and
stripping "irq" results in descriptions starting with numbers which
makes them look too much like counts. This commit just fixes the last
problem.
clobbered at runtime:
dirtybuf -> dtbuf
desiredvnodes -> desvn
numvnodes -> numvn
freevnodes -> frevn
The vmstats column has only 5 characters available for descriptors, but up
to 13 were used. The extras get clobbered at runtime by interrupt values
and/or descriptors on systems with more than 12 interrupt sources.
%slo-z -> %sloz
This one is in the "extended" vmstats area and doesn't get clobbered now.
Removed stale documentation of desvn.
Changed a descriptor:
tfree -> totfr
so that it is consistent with the abbreviations for other free counts
(daefr and prcfr) and thus almost decodeable.
Fixed missing documentation of tfree/totfr. This and everything else
in the extended vmstats area is misdocumented as being in a certain
place in the vmstats column.
This speeds up my testing a bit. Because truncate(1) doesn't allocate
blocks on file system before they are used, it is very useful to
emulate huge file systems:
# truncate -s 16T fs.img
# mdconfig -a -f fs.img
# newfs /dev/mdX
(-t swap can be used as well)
