user nobody and/or setting group nogroup as owner of a file or directory.
Usually at the client side, if there is an username that is not in the
client's passwd database, some clients will send 'nobody@<your.dns.domain>'
in the wire and the NFSv4 server will treat it as an ERROR.
However, if you have a valid user nobody in your passwd database,
the NFSv4 server will treat it as a NFSERR_BADOWNER as its believes the
client doesn't has the username mapped.

When processing async destroys ZFS would leak space every txg timeout
(5 seconds by default), if no writes occurred, until the pool is totally
full. At this point it would be unfixable without a pool recreation.
In addition if the machine was rebooted with the pool in this situation
would fail to import on boot, hanging indefinitely, as the import process
requires the ability to write data to the pool. Any attempts to query the
pool status during the hung import would not return as the import holds
the pool lock.
The only way to import such a pool would be to specify -o readonly=on
to the zpool import.
zdb -bb <pool> can be used to check for "deferred free" size which is where
this lost space will be counted.

For compatibility, 'device windtunnel' is still supported, but one should use
'device adm1030' instead, and this has been updated in GENERIC and NOTES.
This fixes use-after-free, caused by geom_disk, completing same BIO twice
to save extra allocation, and getting BIO_DONE set after the first.

Mellanox hardware driver(s):
- Properly name an inclusion guard
- Fix compile warnings regarding unsigned enums
- Add two new sysctl nodes
- Remove all empty linux header files
- Make an error printout more verbose
- Use "mod_delayed_work()" instead of
cancelling and starting a timeout.
- Implement more Linux scatterlist
functions.

read/write/poll/ioctl, call standard vnode filedescriptor fop. This
restores the special handling for terminals by calling the deadfs VOP,
instead of always returning ENXIO for destroyed devices or revoked
terminals.
Since destroyed (and not revoked) device would use devfs_specops VOP
vector, make dead_read/write/poll non-static and fill VOP table with
pointers to the functions, to instead of VOP_PANIC.

Summary:
If a user uses powerd, or doesn't want to use the cycles monitoring, they can
now suspend the monitoring thread.
While here, reorganize the added prototypes to match existing groupings.

He noticed issues setting this bit in SRRCTL after the queue was up,
so doing it from the sysctl handler isn't enough and may not actually
work correctly.
This commit doesn't remove the sysctl path or try to change its
behaviour. I'll talk with others about how to finish fixing that
before I tackle that.

few changes to drivers, no kernel config was added. As the SoCs are quite
old and the code is unmaintained start the process of removing support by
deleting the header file and code that depends on it along with the macro
SOC_OMAP3. Other Ti SoCs shouldn't be affected, other than for us to have
less code to maintain.
