47212158a0 Fix a problem which appeared to truncate a file to the nearest block boundary
when it is moved to an NFS filesystem from from another filesystem and /bin/mv
failed to set the file ownership during the move.

I believe that this bug is present in STABLE but I have not tested it.  The fix
would be the same in STABLE even though the code has changed quite considerably
in CURRENT.

57585a8e54 Use the same method to determine the time that the process
ended that fork() uses to determine the time that the process
started when calculating the elapsed time.  This prevents the
ac_etime field in the accounting record from getting set to -1
if the process exists for a VERY short period of time.

a16721a13a Move the inline code for waking up writers to a new function
ttwwakeup().  The conditions for doing the wakeup will soon become
more complicated and I don't want them duplicated in all drivers.

It's probably not worth making ttwwakeup() a macro or an inline
function.  The cost of the function call is relatively small when
there is a process to wake up.  There is usually a process to wake
up for large writes and the system call overhead dwarfs the function
call overhead for small writes.

Temporarily nuke TS_WOPEN.  It was only used for the obscure MDMBUF
flow control option in the kernel and for informational purposes
in `pstat -t'.  The latter worked properly only for ptys.  In
general there may be multiple processes sleeping in open() and
multiple processes that successfully opened the tty by opening it
in O_NONBLOCK mode or during a window when CLOCAL was set.  tty.c
doesn't have enough information to maintain the flag but always
cleared it in ttyopen().

TS_WOPEN should be restored someday just so that `pstat -t' can
display it (MDMBUF is already fixed).  Fixing it requires counting
of processes sleeping in open() in too many serial drivers.

f5526ddb48 Implemented an nfs_node hash list lock, similar to what was implemented
in ffs_vget(), and for the same reason: to prevent a race condition that
results in duplicate vnodes/NFSnodes being allocated.

44918dfed7 Re-lookup the buffer if the vnode isn't locked. The previous check for
VBLK vnodes isn't adequate since all NFS nodes aren't locked, either. The
result is a race condition that would lead to duplicate buffers at the
same block offset.

1174c7d121 This fixes a compiler warning, and a cosmetic problem with the linux
emul code when compiling with "options KTRACE".
ktrsyscall() was expecting an array of integers, this was passing the
address of a structure containing an array of integers..
The cosmetic problem was that it was calling the "enter syscall"
trace hook twice - this looks like a cut/paste error/typo.

ffc2aaf2d8 Do not set SCSI_NOSLEEP on every tape command (the exception being during
probes).  Apart from there being no reason to set SCSI_NOSLEEP on every
tape command, this prevents controller drivers from sleeping when resources
are fully utilized causing unecessary "Oops not queued" errors.  This is
only noticed for controllers that can run out of resources like the
27/2842 adaptec controllers.  Before this fix, it is almost impossible to
perform extended tape operations if more than one scsi disk is on the
bus with the tape drive with these controllers.  This does not address a
similar problem that could occur if devices are probed while other targets
are active since SCSI_NOSLEEP will still be set in that case.
