233fb3be1e Add VINUM_MOVE ioctl.
Fix transfer lengths for some ioctls.

Rearrange file: put structs first, then ioctl requests.

ed3e9bf301 struct vinum_ioctl_msg: Add fields verify (for initsd) and blocksize
(for revive and init).

af87ab426c Reduce MAX_IOCTL_REPLY to 1024; the previous value was more than ioctl
could stand.

Define the correct return lengths for a number of ioctls.

Add ioctls VINUM_CHECKPARITY and VINUM_RESETPARITY, still to be fully
implemented.

4fe498363c Add VINUM_SETSTATE_FORCE ioctl for diddling individual object states.
This is a repair tool which can also be used for panicing the system.
Use with utmost care if at all.

60402eb12d Add 'initialized' state for subdisks. After initializing, the subdisk
goes into initialized state, not 'up'.  This makes it easier to ensure
consistency in multi-plex volumes.

update_plex_state: redo transitions from empty and initialized
subdisks to up or reviving, depending on the number of plexes.

dbac8959f7 Add definition of new ioctl (READPOL) for setting the read policy of a
plex.  The code is not yet complete.

fd7505f096 Change the lengths of many ioctl parameters, which occasionally caused
EFAULTS due to sloppy programming.

7f1050341c Change multiline comments to start with a lone /* and end with a */,
apparently in accordance with style(9).

2f4e1ffa11 Remove ioctls VINUM_GETUNMAPPED and VINUM_GETDEFECTIVE (we no longer
have regions).

Add definitions for VINUM_DAEMON, VINUM_FINDDAEMON and VINUM_DAEMON

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.
