If we aggregated status sending with data move and got error, allow status
to be updated and resent again separately. Without this command may stuck
without status sent at all.
When mountd is creating sockets, it iterates over all addresses specified
in the "hosts" array and eventually looks up the network address with
getaddrinfo(). At one point it checks for a numeric address and if it
sees one, it sets a hint parameter to force getaddrinfo to interpret the
host as a numeric address. However that hint is not cleared for subsequent
iterations of the loop and if any hosts seen after this point are host names,
getaddrinfo will fail on the name. The result of this bug is that you cannot
pass a host name to the -h flag.
Unfortunately, the first iteration will either process ::1 or 127.0.0.1,
so the flag is set on the first iteration and all host names will fail
to be processed.
The same bug applies to rpc.lockd and rpc.statd, so fix them too.

Remove dead code.
After the ext2 variant of the "orlov allocator" was implemented,
the case for a negative or zero dirsize disappeared.
Drop the dead code and unsign dirsize given that it can't be
negative anyways.
ext2fs: fix for uninitialized pointer read.
path.ep_bp was being used uninitialized in ext4_ext_find_extent().

Previous throttling implementation approached problem from the wrong side.
It significantly limited useful delaying of TRIM requests and aggregation
potential, while not so much controlled TRIM burstiness under heavy load.
With this change random 4K write benchmarks (probably the worst case for
TRIM) show me IOPS increase by 20%, average latency reduction by 30%, peak
TRIM bursts reduction by 3 times and same peak TRIM map size (memory usage).
Also the new logic does not force map size down so heavily, really allowing
to keep deleted data for 32 TXG or 30 seconds under moderate load. It was
practically impossible with old throttling logic, which pushed map down to
only 64 segments.
Add context pointer and source address to the UDP tunnel callback
These are needed for the forthcoming vxlan implementation. The context
pointer means we do not have to use a spare pointer field in the inpcb,
and the source address is required to populate vxlan's forwarding table.
Make clear in the ipheth(4) hardware notes that this driver is for the
tethering functionality only. Add a "bugs" section to give a pointer
to usbconfig set_config if the device isn't automatically detected.
Add missing error checking for kernel_port_{add,remove}(). Both can fail
for reasons yet unknown; don't make it increment cumulated_error as a kind
of temporary workaround.

Fix null pointer dereference.

Add netmap support to libpcap. Tcpdump and other native pcap clients
can now run directly on netmap ports using netmap:foo or valeXX:YY
as device names.
Modifications to existing code are small and trivial,
the netmap-specific code is all in a new file.
Please be aware that in netmap mode the physical interface is
disconnected from the host stack, so libpcap will steal the traffic
not just make a copy.
For the full version of the code (including linux and autotools support) see
https://code.google.com/p/netmap-libpcap/
New segment at the list head may block all TRIM requests until txg of that
segment can be processed. On my random I/O tests this change reduce peak
TRIM list length from 650 to 450 segments. Hopefully it should reduce TRIM
burstiness when list processing is unblocked.
On FreeBSD gethrtime() implemented via getnanouptime(), that has 1ms (1/hz)
precision. It makes primary sort key (timestamp) collision very possible.
In such situations sorting by secondary key of LBA is much more reasonable
then by totally meaningless zio pointer value.
With this change on multi-threaded synchronous ZVOL read I've measured 10%
throughput increase and average latency reduction.
