- dkwedge_del(): Don't compute a minor number based on partitions, because
wedges don't have partitions. Just provide the unit number to vdevgone().
- dkopen(): Make sure we release all of the locks we've acquired should
opening the parent device fail.
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
so that config_detach() doesn't panic.
(XXX this points to some disagreement between config_attach_pseudo()
and config_detach() over the correct role of pseudo-device cfdata)
unit now. Don't pretend wedges have "partitions".
- Fix a buglet related to opening char and block devices of a wedge
at the same time.
- Add dkwedge_set_bootwedge(), that MD code can call to set booted_device
and booted_wedge appropriately when MD code knows the parent disk and
the start/size of the wedge that was booted from.
disklabels nested inside an MBR "NetBSD" or "386BSD" partition (first
one found is considered authoritative for the disk), or in one of several
known locations for various NetBSD platforms. It can read native or other-
endian disklabels (code is there, but not tested).
If you want to play with this, exercise caution; you can't currently
mountroot on a wedge (setroot() needs some work). Enabled by the
DKWEDGE_METHOD_BSDLABEL kernel option.
