35b5051ab9 complete_rqe: explicitly reinitialize b.b_iodone. This shouldn't have
changed, but we've seen some weird cases of b_iodone
	      being NULL, and they don't make any sense.

which doesn't use request groups.

49ff4debd3 Spring cleaning around strategy and disklabels/slices:
Introduce BUF_STRATEGY(struct buf *, int flag) macro, and use it throughout.
please see comment in sys/conf.h about the flag argument.

Remove strategy argument from all the diskslice/label/bad144
implementations, it should be found from the dev_t.

Remove bogus and unused strategy1 routines.

Remove open/close arguments from dssize().  Pick them up from dev_t.

Remove unused and unfinished setgeom support from diskslice/label/bad144 code.

6dd671ea60 Remove some XXX comments (they're not really gone, just invisible).
Remove declarations for freerq and free_rqg.

Remove DEBUG_RESID code.

freerq: check whether the request is holding a lock, free if so.

free_rqg: remove.  It wasn't being used any more.

Change the Debugger calls to panics.

0ef1c82630 Decommision miscfs/specfs/specdev.h. Most of it goes into <sys/conf.h>,
a few lines into <sys/vnode.h>.

Add a few fields to struct specinfo, paving the way for the fun part.

a01fbbe4ac Include Peter Wemm's renaming and restructuring
Change from lkm to kld

Recover from I/O errors by passing the request to the daemon, except
for plex I/O, which is not fault tolerant.

c285ca1254 Some relatively minor tweaks to enable vinum to be built into a static
kernel as a pseudo-device.  The changes were:
- #ifdef DEBUG -> #ifdef VINUMDEBUG
- opt_vinum.h for holding above config variable
- Fixing up a few stray problems where DEBUG wasn't optional.
- config.c -> vinumconfig.c (there's already a config.o)
- Other *.c -> vinum*.c (wasn't strictly necessary, but done in case we end
  up with something else conflicting later on and we might have to have yet
  more repository copies of files).
- include file paths fixups..  (ie: get them all from the kernel tree
  instead of partly from the kernel and partly from /usr/include/machine)

I've spoken with Greg about this..  I hope this doesn't mess him around
too much..

ef2dbe9885 If I've done this right, revive the vinum code in it's now home after it
was savaged in the blood bath a few hours ago.

721fbc5ae0 config.c:
config_drive:
    Catch an instance of anonymous drives.  Doubtless many remain.

interrupt.c:
  complete_rqe:
    Call logrq to log iodone events if DEBUG_LASTREQS is set.

    Call set_sd_state with setstate_noupdate to avoid buffered I/O out
    of interrupt context.

    Use define DEBUG_RESID instead of constant.

memory.c:
  Remove dead expandrq() function

  Malloc:
    Remove directory component of file names in malloc table.

  Add function vinum_rqinfo (part of the request tracing stuff).

request.c:
  Add function logrq (part of the request tracing stuff).

  vinumstrategy:
    Check whether config needs to be written to disk, do it if so.
    This is a stopgap until the Vinum daemon (bacchusd?  oenologistd?)
    is written.

    If DEBUG_LASTREQS is set, call logrq to log user buffer headers.

  launch_requests:
    Correct format of debug output to console.

    If DEBUG_LASTREQS is set, call logrq to log request elements.

request.h:
  Add definitions for request trace.

state.c:
  set_sd_state:
    Check flags for setstate_noupdate.  If set, don't write the config
    to disk, just set global VF_DIRTYCONFIG flag.  This is part of the
    kludge to avoid writing config from an interrupt context.

vinumext.h:
    Add declaration for vinum_rqinfo, put inside #ifdef DEBUG
    Remove dead macro expandrq

vinumio.h:
  Increase maximum ioctl reply length to 4 kB if DEBUG is set.
  Define VINUM_RQINFO ioctl if DEBUG is set.

vinumioctl.c:
  vinumioctl:
    Change implementation of VINUM_DEBUG ioctl: use a debug flag
    (DEBUG_REMOTEGDB) to decide whether to go into remote debugging or
    not.

    Implement VINUM_RQINFO.

vinumkw.h:
  Define kw_info even when not debugging.

vinumvar.h:
  Define VF_DIRTYCONFIG
  Add pointers to request info to vinum_info if DEBUG is set.
  Define setstate_noupdate
  Define additional debug bits DEBUG_RESID, DEBUG_LASTREQS and
  DEBUG_REMOTEGDB.
