remove the splbio() around the call to launch read requests.
launch_requests:
Move the splbio() protection outside the entire launch_loop. The
previous location was causing problems with IDE drives, where the
call to the strategy routine often did not complete until after
complete_rqe deallocated the request structure.

Check for partition types FS_VINUM and FS_UNUSED. Accept both, but
complain about FS_UNUSED. At a later date, only FS_VINUM will be
accepted.

Add a flag `force' (VF_FORCECONFIG) to force name changes of
existing drives.
config_drive:
If the drive already has a vinum label, and name doesn't match the
specified drive, do it anyway if the 'force' flag is specified.
finish_config:
Reset the `force' flag.

give_sd_to_drive:
If the drive is down, take the subdisk down and don't try to fix
things.
update_plex_config:
Don't try to update the config parameters of a plex which isn't
fully configured (state plex_init or plex_unallocated).
Correctly calculate the amount to trim off a striped or RAID-5 plex
whose size is not a multiple of the stripe size.
/usr/sbin/sysctl -> ${DESTDIR}/sbin/sysctl in some versions of 2.2,
and this link was broken if DESTDIR was set.
Added a SYMLINKS macro. This works the same as LINKS, except it
creates symlinks and the linked-to pathname may be relative. This
is more flexible than LN_FLAGS, since it supports installing
symlinks independently of hard links.
Use `ln -f[s] ...' instead of `rm -f ...; ln [-s] ...' for LINKS and
SYMLINKS. This is equivalent if the target is neither a directory nor
a symlink to a directory.

Remove more (redundant) map timestamp increments from properly
synchronized routines. (Changed: vm_map_entry_link, vm_map_entry_unlink,
and vm_map_pageable.)
Micro-optimize vm_map_entry_link and vm_map_entry_unlink, eliminating
unnecessary dereferences. At the same time, converted them from macros
to inline functions.

(fatal) mismatches between the kernel and userland.
Coalesce flags VINUM_DISKCONFIG and VINUM_READING_CONFIG. They did
essentially the same thing.
Add VINUM_BIGDRIVE for pretending we have macho hardware.

This solved a problem where 'vinum resetconfig' only reset half
the drives.

Change the super device. We now have three super devices:
1. The normal superdevice used by vinum(8).
2. The superdevice used by vinum(8) when compiled with debug support.
3. The superdevice used by the daemon.
This method allows vinum(8) to determine debug mismatches. Also check
correctly for the device type. The old code did not check all bits of
the minor number.

with the new boot loader configuration process. I got a lot of
help from Daniel Sobral, and both Dan and I got help from Mike
Smith. This really belongs in Warner's UPDATING, but he's not
been answering his email recently, so that will wait a little.
Robert Nordier also gave me a lot of help, but he hasn't seen the
last version, and can't be blamed for my errors.
