pointers to an integer via uintptr_t.
Fix an apparent bug that caused a compile failure.
ieee80211_iterate_nodes() takes ic->ic_sta as its first argument on the
onoe module. It had just 'ic' here in the same context, which was a
mismatched argument.
of a sizeof, need to use %z to get the correct type on all our platforms.
Also, convert integers<->pointers via uintptr_t.
(I think Sam's instructions were for me to commit this. If I
misunderstood, then I apologize in advance.)
nice of 0. Doing so can cause an infinite loop because they should be
running, but a nice -20 process could prevent them from doing so.
- Add a new flag KEF_PRIOELEV to flag a thread that has had its priority
elevated due to priority propagation. If a thread has had its priority
elevated, we assume that it must go on the current queue and it must
get a slice.
- In sched_userret() if our priority was elevated and we shouldn't have
a timeslice, yield here until we should.

which holds on to just the data structure and the mutex. (The
existing refcount (fd_refcnt) holds onto the open files in the
descriptor.)
The fd_holdcnt is protected by fdesc_mtx, fd_refcnt by FILEDESC_LOCK.
Add fdhold(struct proc *) which gets a hold on the filedescriptors of
the specified proc..
Add fddrop(struct filedesc *) which drops the fd_holdcnt and if zero
destroys the mutex and frees the memory.
Initialize the fd_holdcnt to one in fdinit(). Normal operations on
the filedesc structure will not change it.
In fdfree() use fddrop() to dispose of the mutex and structure. Hold
the FILEDESC_LOCK() until we have cleaned out the contents and carefully
set the fields to null values during cleanup.
Use fdhold()/fddrop() in mountcheckdirs() and sysctl_kern_file().
for ensuring that a process' filedesc is not shared with anybody.
Use it in the two places which previously had private implmentations.
This collects all fd_refcnt handling in kern_descrip.c
to better keep track of the total amoutn transferred during a
transfer. Seems similar to some code in the NetBSD version.
I notice they have incorporated matches from him so I don't know which
direction it went.

You could turn this off by debug.mpsafenet=0 for full network
stack or via debug.{cp|cx|ctau}.mpsafenet for cp(4), cx(4) and
ctau(4) accordingly.

nice value above 0, set it to 0 so that it may proceed with haste.
This is especially important on ULE, where adjusting the priority
does not guarantee that a thread will be granted a greater time slice.
Now only things that are different between us and NetBSD show up.
Means that these files are more of NetBSD style in some places but
since thay are NetBSD files, um, that's ok.

do things correctly from an aliasing perspective. Put the
vop_generic_args element as the first element for all the vop_*_args
and adjust the code to take the address of that instead of the
structure.
OK'd based on a vague description by: phk
