- I can't seem to reproduce the warning I got from WITNESS anymore.
- The fix was wrong. Since a uidinfo struct is a member of proc, it
makes sense for the locking order to be such that you are allowed to
hold proc and then grab the uidinfo lock.
user actually editing the output. Too many people were rampantly abusing
this feature via "pkg_version -c | sh" without really being cognizant
of the dangers involved (ports upgrade kits) or the fact that it
just plain wasn't designed for it (dependencies). We'll try to keep
people from shooting themselves in the foot.
Will be MFC-ed to RELENG_4 and RELENG_3 after cooling-off period.
- Use swi_* function names.
- Use void * to hold cookies to handlers instead of struct intrhand *.
- In sio.c, use 'driver_name' instead of "sio" as the name of the driver
lock to minimize diffs with cy(4).
- Add a set of MI helper functions for interrupt threads:
- ithread_create() creates a new interrupt thread
- ithread_destroy() destroys an interrupt thread
- ithread_add_handler() attaches a new handler to an interrupt thread
- ithread_remove_handler() detaches a handler from an interrupt thread
- Rename sinthand_add() and sched_swi() to swi_add() and swi_sched()
respectively so that they live in a consistent namespace.
- struct intrhand is no longer a public type. It would be private to
kern_intr.c but the current implementation of fast interrupts on the
alpha requires the type to be exported. However, all handlers should
be treated as void * cookies in the way that new-bus treats them. This
includes references to software interrupt handlers.
This mistake seems to have been benign until very recently, probably
until msmith's PCI code reshuffle which cleaned up a lot of things.
Still, my AIC7770 doesn't work again, but it at least probes the
EISA bus now.
will only display sleep mutexes held by the current process.
- Clean up some nits in the witness_display() function and add a ddb
command 'show witness' that dumps the hierarchy and order lists to the
console.
- Use queue(3) macros where appropriate.
- Resort the spin lock order list so that "com" is before "sched_lock".
Also, add appropriate #ifdef's around SMP and i386-specific mutexes.
- Add two new mutexes used to protect the ithread lists and tables to the
order list.

- show ktr_first display the first entry
- show ktr_next display the next entry
- show ktr display the entire buffer
The /v modifiers continue to work as described previously.

only the boot processor should be running in the comments.
- Initialize curproc to point to each CPU's respective idleproc if their
curproc is NULL.
- Keep track of the number of context switches performed by idleproc.
of returning an error code to the caller, NFS server op routines
must themselves build an error reply and return 0 to the caller.
This is achieved by replacing the erroneous return statements with
code that jumps forward to the op function's reply code. We need
to be careful to ensure that the 'struct mount' pointer is NULL
though, so that the final vn_finished_write() call becomes a no-op.
