Add correct support for v_object management, so mmap() operation should
work properly.
Add support for extattrctl() routine (submitted by semenu).
At this point nullfs can be considered as functional and much more stable.
In fact, it should behave as a "hard" "symlink" to underlying filesystem.

separately (nfs, cd9660 etc) or keept as a first element of structure
referenced by v_data pointer(ffs). Such organization leads to known problems
with stacked filesystems.
From this point vop_no*lock*() functions maintain only interlock lock.
vop_std*lock*() functions maintain built-in v_lock structure using lockmgr().
vop_sharedlock() is compatible with vop_stdunlock(), but maintains a shared
lock on vnode.
If filesystem wishes to export lockmgr compatible lock, it can put an address
of this lock to v_vnlock field. This indicates that the upper filesystem
can take advantage of it and use single lock structure for entire (or part)
of stack of vnodes. This field shouldn't be examined or modified by VFS code
except for initialization purposes.

more similar problems like this one with calls to bdg_forward().

Add support for constructing a table of critical section regions in
the firmware image. The kernel driver will soon have support for
single stepping the sequencer outside of a critical region prior
to starting exception handling.
ahc_pci.c:
Bring back the AHC_ALLOW_MEMIO option at least until the
memory mapped I/O problem on the SuperMicro 370DR3 is
better understood.
aic7xxx.c:
If we see a spurious SCSI interrupt, attempt to clear it and
continue by unpausing the sequencer.
Change the interface to ahc_send_async(). Some async messages
need to be broadcast to all the luns of a target or all the
targets of a bus. This is easier to achieve by passing explicit
channel, target, and lun parameters instead of attempting to
construct a device info struct to match.
Filter the sync parameters for the PPR message in exactly the
same way we do for an old fashioned SDTR message.
Correct some typos and correct a panic message.
Handle rejected PPR messages.
In ahc_handle_msg_reject(), let ahc_build_transfer_msg() build
any additional transfer messages instead of doing this inline.
aic7xxx.h:
Increase the size of both msgout_buf and msgin_buf to
better accomodate PPR messages.

Update for change in ahc_send_async() parameters.

aic7xxx_pci.c:
Check the error register before going into full blown PCI
interrupt handling. This avoids a few costly PCI configuration
space reads when we run our PCI interrupt handler because another
device sharing our interrupt line is more active than we are.
Also unpause the sequencer after processing a PCI interrupt.
