giant must be acquired prior to the proc lock, so ptrace must require giant
still.

ums module, and allow for up to five attempts to open the device, with
two-second pauses in between, to allow time for USB controllers and
devices to probe and attach. My Gigabyte P4 Titan 848P motherboard has
a total of 15 ports on four hubs hanging off four controllers, and needs
at least half of that ten-second allowance to get ready.

multicast hash are written. There are still two distinct algorithms used,
and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
additional argument).

is that fseeko() fails in very predictable and frequent ways on ia64.
This is because the offset is actually an address in the process'
address space, which on ia64 can be larger than long (for lseek) or
off_t (for fseeko). The crux is the signedness. The register stack
and memory stack are in region 4 on ia64. This means that the sign bit
is 1. The large positive virtual address is wrongly interpreted as
a negative file offset.
There's no quick fix. Even if you get around the API by using a
SEEK_SET up to LONG_MAX and follow it up with a SEEK_CUR for the
remainder, the kernel simply cannot deal with it. and the second
seek will just fail.
Therefore, this change does not actually fix the root cause. It just
makes sure we're not spitting out all kinds of garbage or that the
get_struct() function in particular does not cause truss(1) to exit.
This, I might add, invariably happened way too soon for truss(1) to
be of any use on ia64...

Folks that want to watch PHY errors can still get the statistics

o reject scan requests for a device that isn't marked up
This fixes a problem where requesting a scan before marking the device
up would cause a panic because the current channel was set to "any" (0xffff).
o correct a read-lock assert in in_pcblookup_local that should be
a write-lock assert (since time wait close cleanups may alter state)

one of the threads blocked on the turnstile just woken up, then the

during priority propagation.
