f5dd123567 Completely turn off RSVP intercept when a socket being used for that purpose
is PRU_DETACHed.  This solves the problem that RSVP would not come up inm

8395ec3635 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.

09298b57cf 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

688f94b143 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.

dc33f04058 Re-lookup the buffer if the vnode isn't locked. The previous check for

9453deea20 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.

68ad3472c8 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.
