umsX character device returns a read error. Update devd.conf rules
to use "DEVFS" events which are generated after that the umsX
character device node has been created/destroyed, and then there
should be no need for moused to wait up to 10 seconds for umsX to
be ready. Opening umsX should not fail except if the kernel is low
on memory. In that case the user can replug the USB mouse or use
"usbconfig" to reset the device. In case of USB mouse devices,
moused should neither retry to open its character device,
once the first read error has happened. This is an indication
of device detach.

Also while there, make sense polling use reported for each node separately
instead of reporting accumulated total status.

The previous commit to enable CLRDMASK setting didn't do it at all
correctly for non-aggregate sessions - so the CLRDMASK bit would be
cleared and never re-set.
* move ath_tx_update_clrdmask() to be called by functions that setup
descriptors and queue frames to the hardware, rather than scattered
everywhere.
* Force CLRDMASK to be set on all non-aggregate session frames being
transmitted.
* Use ath_tx_normal_comp() now on non-aggregate sessoin frames
that are queued via ath_tx_xmit_normal(). That way the TID hwq is
updated and they can trigger (eventual) filter frame queue resets
and software retransmits.
There's still a bit more work to do in this area to reverse the silly
short-sightedness on my part, however it's likely going to be better
to fix this now than just reverting the patch.
Thanks to people on the freebsd-wireless@ mailing list for promptly
pointing this out.

libtirpc: be sure to free cl_netid and cl_tp
When creating a client with clnt_tli_create, it uses strdup to copy
strings for these fields if nconf is passed in. clnt_dg_destroy frees
these strings already. Make sure clnt_vc_destroy frees them in the
same way.

have the following configuration:
tank
tank/foo
tank/foo@snap
tank/bar
tank/bar@snap
We can execute:
# zfs destroy -t tank@snap
eventhough tank@snap doesn't exit.
Unfortunately it is not possible to do the same with recursive rename:
# zfs rename -r tank@snap tank@pans
cannot open 'tank@snap': dataset does not exist
...until now. This change allows to recursively rename snapshots even if
snapshot doesn't exist on the starting dataset.

The code builds a map of regions that were freed. On every write the
code consults the map and eventually removes ranges that were freed
before, but are now overwritten.
Freed blocks are not TRIMed immediately. There is a tunable that defines
how many txg we should wait with TRIMming freed blocks (64 by default).
There is a low priority thread that TRIMs ranges when the time comes.
During TRIM we keep in-flight ranges on a list to detect colliding
writes - we have to delay writes that collide with in-flight TRIMs in
case something will be reordered and write will reached the disk before
the TRIM. We don't have to do the same for in-flight writes, as
colliding writes just remove ranges to TRIM.

This work includes some important fixes and some improvements obtained
from the zfsonlinux project, including TRIMming entire vdevs on pool
create/add/attach and on pool import for spare and cache vdevs.

gone rule. Optimise use of channels so that when a channel
is not ready another channel is used. Instead of using the SOF interrupt
use the system timer to drive the host statemachine. This might
give lower throughput and higher latency, but reduces the CPU usage
significantly. The DWC OTG host mode support should not be considered
for serious USB host controller applications. Some problems are still
seen with LOW speed USB devices.

MFi386: revision 238792
Introduce curpcb magic variable.
builtin is processed specially and thus the `: > file' syntax for example
will cause premature termination of the current shell on redirection-error.
The `true' builtin on the other-hand is not included in this special
processing (for compatibility reasons to satisfy legacy scripts programmed
for systems where `true' is not a builtin).
Change bare `: > file' syntax into `true > file' syntax to prevent premature
shell termination in the event of redirection-error.
NOTE: Instances of `: > file' that appear within a sub-shell have been left
unmodified as these will not cause premature termination of the main script.

as an optimization, but we are getting closer to supporting
applications and/or kernels that change the (FreeBSD i386) default
rounding precision from FP_PD to FP_PE and never change it back,
and this requires the STRICT_ALIGN()s that were added to support
FP_PE to actually work in all precisions.
