76714993c6 Include Peter Wemm's renaming and restructuring
Change from lkm to kld

Remove BROKEN_GDB kludge (it's not needed with klds)

Add code for interfacing with daemon

Modify device minor number encoding, use selector functions which also
permit anonymous plexes and subdisks.

Remove code for 2.x support.

Change messages to omit obvious words like 'plex' and 'subdisk.

give_plex_to_volume: invalidate subdisks being given to a plex which
is part of a volume with other plexes.

give_sd_to_plex: keep track of plex size in all cases

lock drives before closing them, to keep the daemon from getting
confused.

config_drive: handle partition type errors more gracefully

config_subdisk: set subdisk state correctly

find_drive, find_drive_by_dev, find_subdisk, find_plex, find_volume:
  set VF_NEWBORN flag when a new object is created

config_drive:
  Handle partition_status returns more cleverly.
  Replace the device name in some cases where it got overwritten.

config_subdisk:
  add parameter `update'.  If the object already exists, exit without
  any changes.
  Set state correctly.

config_plex, config_volume:
  add parameter `update'.  If the object already exists, exit without
  any changes.

parse_config:
  move read function to vinum_scandisk.
  add parameter `update' to pass to config_<object>.

remove_<object>_entry:
  print a message when the object is removed.

update_plex_config:

Modify manner of determining when module is idle

Modify device minor number encoding, use selector functions which also

Move vinum_scandisk to vinumio.c

Remove myproc kludge

Keep track of open volumes by flag, not by pid (the pids caused some
problems with the lock manager).

free_vinum:
  Remove unmapped and defective regions from plexes.
  Wait for daemon to stop before returning

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..

was savaged in the blood bath a few hours ago.

8b71433847 Don't close drives when called from interrupt context, set a flag for
the top half to do it.

Put in a dubious check for subdisk integrity when trying to bring
up a plex where others are already up.  This particular kludge is
crying out for a rewrite of the whole state code.

Add code to set_plex_state and set_volume_state to defer updates when
called from an interrupt context.  This doesn't happen yet, but it
could do.

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.
