This change adds tests/ directories in the source tree to create various
subdirectories in /usr/tests/ and to install placeholder Kyuafiles for
them.
the relevant hierarchies are: cddl, etc, games, gnu and secure.
The reason for this is to simplify the addition of new test programs for
utilities or libraries under any of these directories. Doing so on a
case by case basis is unnecessary and is quite an obscure process.

and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.
New ZFS property volmode and sysctl vfs.zfs.vol.mode allow switching ZVOL
between three modes:
geom -- existing fully functional behavior (default);
dev -- exposing volumes only as raw disk device file in devfs;
none -- not exposing volumes outside ZFS.
The "dev" mode is less functional (can't be partitioned, mounted, etc),
but it is faster, and in some scenarios with untrusted consumers safer.
It can be useful for NAS, VM block storages, etc.
The "none" mode may be convenient for backup servers, etc. that don't
need direct data access.
Due to the way ZVOL is integrated with main ZFS code, those property
and sysctl are checked only during pool import and volume creation.

concatenates the DOF tables into one section. Previously, the USDT init
code in drti.o would only look at the first table in the DOF section; with
this change, it iterates over all the tables, passing each DOF table to
the kernel.

This fixes the tst.resize1.d and tst.resize2.d DTrace tests, which have
been failing since r261122 since they were causing dtrace(1) to attempt to
allocate and use large amounts of memory, and get killed by the OOM killer
as a result.

Upon the availability of zfsd, the zpool manpage on relevant branches should

The limitation was introduced in r178556 without any note or comment.
It seems pretty artificial and now it leads to problems like the following:
$ dtrace -x bufsize=17m -n ...
dtrace: processing aborted: Memory allocation failure
OpenSolaris and illumos never had this limitation.

emitting the DIE for the type of that member. ctfconvert can not
handle this properly and will calculate a wrong member bit offset.
Same struct/union type from different .o file will be treated as
different types when their member bit offsets are different, and
gets added/merged multiple times. This will in turn cause many other
structs/pointers/typedefs that refer to the duplicated struct/union
gets added/merged multiple times and eventually causes numerous
duplicated CTF types in the kernel.debug file.
The simple workaround here is to make use of DW_AT_byte_size attribute
of the member DIE to calculate the bits occupied by the member's type,
without actually resolving the type.

like GCC could generate DW_TAG_base_type DIE without a name.
Note that we didn't need this before because the old libdwarf

(64MB). Even if we would find one somehow, ZFS kernel code rejects such
devices. It is funny to look on attempts to read 4 256K vdev labels from
1.44MB floppy, though it is not very practical and quite slow.
