Manual pages from OpenSolaris svn_134 are still properly CDDL licensed
but I have been informed that the parts from s11ex are uncertain even
if they contain a CDDL header.
Improved alignment for a maximum width of 80 characters.
Mark unsupported parts as such.

are linked with libraries they don't use:
- zinject doesn't use libavl
- ztest doesn't use libz
- zdb uses neither libavl nor libz
- zfs uses neither libbsdxml nor libm, nor libsbuf
- zpool uses neither libbsdxml nor libm, nor libsbuf
In addition, libzfs needs libm because it uses pow(), however it isn't
linked with -lm. This went unnoticed because all its users had -lm before.

non-legacy mountpoints. It is better to be able to rename such file systems and
let them be mounted in old places until next reboot than using live CD, etc. to
rename with remount.
This is implemented by adding -u option to 'zfs rename'. If file system's
mountpoint property is set to 'legacy' or 'none', there is no need to specify -u.
Update zfs(8) manual page to reflect this addition.

It is possible for file systems with 'mountpoint' preperty set to 'legacy'
or 'none' - we don't have to change mount directory for them.
Currently such file systems are unmounted on rename and not even mounted back.
This introduces layering violation, as we need to update 'f_mntfromname'
field in statfs structure related to mountpoint (for the dataset we are
renaming and all its children).
In my opinion it is worth it, as it allow to update FreeBSD in even cleaner
way - in ZFS-only configuration root file system is ZFS file system with
'mountpoint' property set to 'legacy'. If root dataset is named system/rootfs,
we can snapshot it (system/rootfs@upgrade), clone it (system/oldrootfs),
update FreeBSD and if it doesn't boot we can boot back from system/oldrootfs
and rename it back to system/rootfs while it is mounted as /. Before it was
not possible, because unmounting / was not possible.

cddl/contrib/opensolaris/lib/libzfs/common/libzfs_import.c:
Add the "zpool labelclear" command. This command can be
used to wipe the label data from a drive that is not
active in a pool. The optional "-f" argument can be
used to treat an exported or foreign vdev as "inactive"
thus allowing its label information to be cleared.

cddl/contrib/opensolaris/cmd/zpool/zpool_main.c:
The "zpool status" command reports the "last seen at"
device node path when the vdev name is being reported
by GUID. Augment this code to assume a GUID is reported
when a device goes missing after initial boot in addition
to the previous behavior of doing this for devices that
aren't seen at boot.
cddl/contrib/opensolaris/lib/libzfs/common/libzfs_pool.c:
In zpool_vdev_name(), report recently missing devices
by GUID. There is no guarantee they will return at
their previous location.
cddl/contrib/opensolaris/lib/libzfs/common/libzfs_pool.c:
o Add zpool_pool_state_to_name() API to libzfs which converts a
pool_state_t into a user consumable string.
o While here, correct constness of make zpool_state_to_name()
and zpool_label_disk().

For snapshots, this is the same as COMPRESSRATIO, but for
filesystems/volumes, the COMPRESSRATIO is based on the data "USED" (ie,
includes blocks in children, but not blocks shared with the origin).
This is needed to figure out how much space a filesystem would use if it
were not compressed (ignoring snapshots).

OpenSolaris and ZFS header files. These changes are sufficient
to allow a C++ program to use the libzfs library.
Note: The majority of these files already included 'extern "C"'
declarations, so the intention of providing C++ compatibility
already existed even if it wasn't provided.
cddl/compat/opensolaris/include/assert.h:
Wrap our compatibility assert implementation in
'extern "C"'. Since this is a compatibility header
I matched the Solaris style of doing this explicitly
rather than rely on FreeBSD's __BEGIN/END_DECLS macro.

Rename parameters in function declarations that conflict

In C, nested structures are visible in the global namespace,
but in C++, they take on the namespace of the structure in
which they are contained. Flatten nested structure
definitions within struct zfs_cmd so these structures are
visible in the global namespace when compiled in both
languages.

- zfs diff.
- zpool split.
- Snapshot holds.
- zpool import -F. Allows to rewind corrupted pool to earlier
