This is some of the worst code I've had to wade through in
ages and I don't want to have to start from scratch again next time.

fsync()' problem
This is another, perhaps slightly less urgent, 2.2 last-minute candidate.

(phk's) sysctl framework, and I needed special code to disambiguate
the VFS_GENERIC node from the VFS_VFSCONF leaf, so I only converted
the leaves to the FreeBSD framework. The error handling isn't quite
right. CSRGS's sysctls seem to return ENOTDIR too much and FreeBSD's
sysctls don't agree with the man page.
instead of all hardcoded assumptions historically used
(i.e. sizeof(long) == 4)
Use MAXLOGNAME == 17 for stricter setlogin() size checking. Since
it rounds up to 20, all sizes remains the same
the quality of the hash distribution. This does not fix a problem dealing
with poor distribution when using lots of IP aliases and listening
on the same port on every one of them...some other day perhaps; fixing
that requires significant code changes.
The use of xor was inspired by David S. Miller <davem@jenolan.rutgers.edu>
and getvfsbyname() interfaces. The new interfaces are now hidden from
applications unless _NEW_VFSCONF is defined. The new vfsconf interfaces
don't work yet.

this fixes a problem that anybody with vty access can panic the system.

The sequencer expects untagged transactions to have the SCBID of the
transaction in the "busy target" array. So, ensure that the busy entry
is up to date for the target in this case. The new identify code in the
sequencer that performs additional sanity checking got caught up when a
tagged transaction created an untagged request sense.
In ahc_handle_seqint, ensure that the target ID is taken from the right
place. In the case of a selection, the ID is in SCSIID. In the case of
a reconnection it is found in SELID.
missing-parentheses bug, but this exposed a misplaced vfs_busy_pages().
This bug cost a factor of 2.5-3 in nfsv3 write performance! It should
be fixed in 2.2.
Removed some debugging code that gets triggered often in normal
operation. There are still many backwards diagnostics (#define
DIAGNOSTIC gives no diagnostics).

Print the stack pointer together with the frame pointer in the trap,
syscall and interrupt messages. The frame pointer is not very useful
for locating syscall args since syscall functions don't have a frame
pointer.
Print all the numbers in the trap, syscall and interrupt messages in
the default radix. The syscall number was confusing because it was
printed in decimal.
Use %#n format more and 0x%x less. 0x%x of course doesn't work with
a variable radix. ddb is now fairly consistent about using %+#n to
print all numbers. It omits the '+' for signed numbers the '#' in a
few cases (e.g., for function args) to save space.
