a9dd30b96b revision 1.40 backed out the removal of PCATCH in a tsleep allowing
an infinite loop if a signal is delivered here.
remove it again, this still ought to be revisited as the error should
probably be returned.

0ea9d6fbc7 Correct printf format for pointers to avoid compilation warnings on
alpha.

Modify the manner in which we lock RAID-5 plexes.  This appears to
solve some of the elusive panics we have seen with corrupted buffer
headers (specifically the zeroed-out b_iodone field).

dbd8153d5e Change the name of the define 'SPACETAB' (originally 'isspace') to
'iswhite'.  The original change was required because of name
conflicts.

command).

5756902abc Add function moveobject, which currently moves subdisks to different
drives.  This function just does the low-level configuration changes;
the resultant subdisk is stale if it previously had any contents,
otherwise it is empty (i.e. in need of initializing if it's RAID-5).
We still need to handle getting the contents moved over, but the
current version will suffice to migrate subdisks from a disk which has
failed.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

3e2c6ca3b9 Removal of sys/device.h
- Move intrhook stuff into kernel.h
- Remove all occurrences of #device <device.h>
- Add kernel.h were necessary (nowhere)
- delete device.h

This file contained the structures for cfdata (old style config) and is no
longer used. It was included by most drivers.

It confuses the remote debugger as the definition of 'struct device' in
device.h is found before the one in bus_private.h.
