to in_rtrequest(); the radix head lock is already acquired before
rnh_walktree is called in in_rtqtimo_one(). This avoids a recursive
acquisition that is no longer permitted in 8.x due to use of an rwlock
for the radix head lock.

msdosfs_unmount() and ffs_unmount() exit early after getting ENXIO.
However, dounmount() treats ENXIO as a success and proceeds with
unmounting. In effect, the filesystem gets unmounted without closing

register instead of AAC_RX_FWSTATUS, as that is the way it's done in
Adaptec's vendor driver and in the Linux drivers. (The same applies
to aac_rkt_get_fwstatus as well.)
However, a concern has been raised about the compatibility of this
change and old hardware / firmware versions. In the absense of
specific information, revert to the original behaviour if the firmware
does not support the "New comm." interface. Users of old cards or
firmware haven't reported the problems that are potentially solved by
switching to OMR0.
It is only really necessary for open(2)'s third argument, which is optional and
obtained through stdarg(3). open(2)'s third argument is 32bit and we pass 64
bits. On little endian it works, because we take lower 32 bits, but on big
endian platforms we take upper 32 bits, so we end up with 0.

different cpu is still assigned to that vector by never clearing idt
entries. This was only provided as a debugging feature and the bugs
are caught by other means.
- Drop the sched lock when rebinding to reassign an interrupt vector
to a new cpu so that pending interrupts have a chance to be delivered
before removing the old vector.

- protect againtst recursions,
- add new devices detection using ata_identify().
Improve ata_identify():
- do not add duplicate device if device already exist.
Rework SATA hot-plug events handling. Instead of unsafe duplicate
implementation use common ata_reinit() to handle all state changes.
All together this gives quite stable and robust cold- and hot-plug operation,
invariant to false, lost and duplicate events.
properly. Otherwise the minimum of 1 is used and you can
only insert a single partition/slice and only at sector
0 (index 1).
o When adding a partition/slice, recalculate the index after
the start and size of the partition/slice are adjusted to
make them a multiple of the track size. Since the precheck
method sets the index based on the start of the partition
as provided by the user, we know that we're off by at most
1 and adjusting the index is safe.
