from 2000 bytes to 20 Kbytes, which now matches the buffer size used for
NGM_BINARY2ASCII conversions.
The aim of this change is to allow for bigger binary structures to be
managed via netgraph ASCII messages, until we come up with an API
improvement which would get rid of such arbitrary hardcoded limits.

bottom of the manpages and order them consistently.
GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

microframe slot was not in the smask. The problem was that the EHCI driver was
then thinking that the transfer was immediately complete in some cases. Which
could lead to freeze-like situations, which can be recovered by unplugging the
USB device.

USB enumeration lock is locked, then the USB stack fails to resume the device
because locking the USB enumeration lock is part of the resume procedure. To
solve this issue a new lock is introduced which only protects the suspend and
resume callbacks, which can be dropped inside the usbd_do_request_flags()
function, to allow suspend and resume during so-called enumeration operations.

- Make sure that when you kick the streams you add correctly
using a 16 bit unsigned.
- Make sure when sending out you allow FWD-TSN to skip over
and list the ACKED chunks in the stream/seq list (so the
rcv will kick the stream)

- Slide the map at the proper place.
- Mark the bits in the nr_array ONLY if there
is no marking.
- When generating a FWD-TSN we allow us to skip past
ACKED chunks too.

labeled iretq instruction.
Suppose that multithreaded process executes two threads, currently
scheduled on different processors. Let assume that thread A executes
using %cs or %ss pointing into the descriptor from LDT. If IPI comes
which handler does not return by jump to doreti, and meantime thread B
invalidates descriptor pointed to by %cs or %ss, then iretq from IPI
handler could fault.
Routing the return by doreti_iret allows kernel to catch the situation
and recover from it by sending signal to the usermode.

frame upon segment register load fault. The doreti procedure does not
load segment registers when returning to the kernel frame, and current
values in the segment descriptor cache already allow the kernel mode
to run, not modified by faulted loaded.

ZFS still like to open all vdevs, close them and open them again,
which in turn provokes taste traffic anyway.
I don't know of any clean way to fix it, so do it the hard way - if we can't
open provider for writing just retry 5 times with 0.5 pauses. This should
elimitate accidental races caused by other classes tasting providers created on
top of our vdevs.

That breaks several output, where the most notable is textdump output.
Fix this by having configurable callbacks passed to witness_list_locks()
and witness_display_spinlock() for printing out datas.

user sets up a socket to a server sends data and closes
the socket before the server has called accept(). It used
to NOT work at all. Now we add a flag to the assoc and
defer assoc cleanup so that the accept will suceed.
