transferred, do it in complete_rqe instead.
launch_requests: Replace the inadvertently removed splbio() around the
main loop. It may not be necessary, but the biggest
test of this stuff are IDE disks, which I'm not
using.
Remove throttling code, I'm pretty sure it's not
needed any more.
Don't set B_ORDERED, it's not necessary either.

build_rq_buffer: Don't lose the B_ORDERED bit, it still has some
residual meaning. To do this right, Vinum needs to
look at the B_ORDERED bit and order the transfer
across all disks involved. That's an exercise for
another day.

Describe stop -f to stop when config updates are disabled.
Explain in more detail why Vinum needs its own partition type, and why
you can't make it the c partition.
Implicitly-sanctioned-by: jkh
The driver constructs a fake disklabel that makes the 'a' partition
cover the entire DVD-RAM disk. This cannot be changed from the user
side. This solution was chosen because most DVD-RAM will have a
UDF (or until we have that CD9660) filesystem on it covering the
entire disk, its not really thought as a real random access device.
This might change over time, but for now this is what we have, and
it is compatible with CDROM's etc, that makes using the minidisk
subsystem less than ideal, because of !modulo BDEV_SIZE blocks.
Also, add a cross reference to pkg_info(1) in pkg_version(1). Finally,
in pkg_version(1), don't put a period at the end of the list of see also
man pages.

o Allow use of "G" in label editor to stand for gigabytes. This
is actually an unrelated patch which I meant to commit separately
but what the heck, it's late.

just the first one.
* Don't reserve extra memory for the prom console unless the platform
actually uses it.
* Fix some historical confusion and a minor bug in the message buffer
initialisation.

as they ought to be. The description of SA_RESTART was a little
unobvious to me in the man page, so i missed it. Thanks to Bruce for
spotting this.

replaces an older attempt to silence vinum(8) when started in
single-user mode.
Add entries for vinum_raid[45].
Replace the preprocessor variable name CDEV_MAJOR with
VINUM_CDEV_MAJOR.

vinum_lvi: Change line spacing. This is still not right.
Change checks for striped or RAID-5 plexes to a macro 'isstriped',
which now also includes RAID-4.
Change checks for RAID-5 plexes to a macro 'isparity', which now also
includes RAID-4.
vinum_lsi: If the subdisk is initializing or reviving, don't wait a
whole second to check whether it's advancing; wait in increments of 50
ms up to 1 second. This makes for a barely perceptible delay.

enabled and print a warning message in varous places if they are not.
Fix typos in comments.
Change some indents to approach style(9).
initvol: If init fails, place the subdisks in a "down" state.
vinum_start(): If we're starting a plex, try doing it directly. It's
possible that the state of the plex differs from that of the subdisks,
for example if somebody has used 'setupstate'.
New functions vinum_raid4 and vinum_raid5 to create RAID-4 and RAID-5
volumes, analagous to vinum_mirror and vinum_stripe.
vinum_checkparity: Don't try to check the parity of a non-parity plex,
print a rude remark instead.

VINUM_BDEV_MAJOR and VINUM_CDEV_MAJOR respectively.
Set DRIVE_MAXACTIVE and VINUM_MAXACTIVE to 30000, effectively
disabling the request limitation code. This code was added as an
attempt to escape from a bug which seems to have gone away, and it's
very likely I'll remove the code Real Soon Now, but I don't want to do
it just yet.
struct drive: Remove references to vnode pointers, including debug
output. Vinum now talks directly to the device driver. Instead, add
a dev_t.
enum plexorg: Add an instance for RAID-4.
Change checks for striped or RAID-5 plexes to a macro 'isstriped',
which now also includes RAID-4.
