Make the alias list a SLIST.
Drop the "fast recycling" optimization of vnodes (including
the returning of a prexisting but stale vnode from checkalias).
It doesn't buy us anything now that we don't hardlimit
vnodes anymore.
Rename checkalias2() and checkalias() to addalias() and
addaliasu() - which takes dev_t and udev_t arg respectively.
Make the revoke syscalls use vcount() instead of VALIASED.
Remove VALIASED flag, we don't need it now and it is faster
to traverse the much shorter lists than to maintain the
flag.
vfs_mountedon() can check the dev_t directly, all the vnodes
point to the same one.
Print the devicename in specfs/vprint().
Remove a couple of stale LFS vnode flags.
Remove unimplemented/unused LK_DRAINED;
lockrange: correctly expand rangelock struct, including expanding a
null struct. Previously lockrange would attempt to lock a
NULL pointer under these circumstances.

aligned. If I recall correctly, this is to ensure apic_imen can be
accessed in a single bus cycle. Also, use TEXT_ALIGN rather than a
.align 2 (which means 2 byte align on ELF and 4 byte align on a.out)
directory. Also, update arguments of NDINIT for both newstat and newlstat.
While I'm at it, fix style bugs in all {s|ls|fs}tat syscalls.

egid will be twice in the set and that setting cr_groups[0] will change egid.
This is simply solved by ignoring cr_groups[0]. That is; linux_getgroups does
not return cr_groups[0] and linux_setgroups does not touch it.

know if and when an unimplemented or obsoleted syscall is being used. Make the
message more end-user friendly.
And as long as we're here, rename some unimplemeted syscalls (linux_phys ->
linux_umount2, linux_vm86 -> linux_vm86old, linux_new_vm86 -> linux_vm86).
Change prototype for linux_newuname from `struct linux_newuname_t *' into
`struct linux_new_utsname *'. This change is reflected in linux.h and
linux_misc.c.

Lastly, make line-continuation and indentation more uniform.
In lookup() however it's the other way around as we need to supply the
dev_t for the vnode, so devfs still has a copy of it stashed away.
Sourcing it from the vnode in the vnops however is useful as it makes
a lot of the code almost the same as that in specfs.
specfs version of the same ops. Merging with phk's dev_t changes is not yet
complete.
i.e. devfs still uses it's own devsw pointer rather than following
devsw(a_vp->v_rdev), and it's own copy of the dev_t.
This fixes some broken actions re: syscons and DEVFS due to bitrot in
devfs vops.
creation of /dev/drum via calling swapon. However, the make_dev has a
bogus (insofar that it hasn't been added yet) cdevsw, so later we end
up crashing with a null pointer dereference on the swap vp's specinfo.
The specinfo points to a dev_t with a major of 254 (uninitialized), and
we get a crash on its d_strategy being called.
The simple solution to this is to call cdevsw_add before the make_dev
is ever used. This fixes the panic which occurred upon swapping.
in 4 byte chunks. It turns out that with the 82c169C on the Netgear
FA-310TX Rev D2, if you tell the chip you have reserved a buffer of 1518
bytes, it will actually treat it as 1516 bytes since 1518 is divisible
by four. Consequently, a packet of 1514 bytes will always end up consuming
two buffers: the last coupleof bytes will spill over into the next
descriptor. This causes the pn_rx_bug_war() routine to trip unnecessarily.
I'm not sure if the 82c169B or 82c168 chips behave the same way; I'll
have to check them. In any case, this change should work just as well
with them. Note that the FA-310TX Rev D2 also has a Broadcom PHY
instead of a Level One LXT970 PHY, however this shouldn't make any
difference as far as the driver is concerned.
This change also allows me to do a way with one rounding overation in
pn_rx-buf_war().
initialized subdisks.
Tidy up some comments.
Eliminate sddownstate(); it wasn't being used any more. Return
REQUEST_DOWN instead.
Add setstate_by_force() to implement the VINUM_SETSTATE_FORCE ioctl
for diddling individual object states. This is a repair tool which
can also be used for panicing the system. Use with utmost care if at
all.
avoids a race condition where multiple RAID-5 subdisks are being
revived at the same time. The locks should also prevent conflicts
with user requests on concatenated and striped plexes, but this needs
more work.
Tidy up some comments.
