Add a new zfs property, "redundant_metadata" which can have values "all" or
"most". The default will be "all", which is the current behavior. When set
to all, ZFS stores an extra copy of all metadata. If a single on-disk block
is corrupt, at worst a single block of user data (which is recordsize bytes
long) can be lost.
Setting to "most" will cause us to only store 1 copy of level-1 indirect
blocks of user data files. This can improve performance of random writes,
because less metadata has to be written. In practice, at worst about
100 blocks (of recordsize bytes each) of user data can be lost if a single
on-disk block is corrupt.
The exact behavior of which metadata blocks are stored redundantly may change
in future releases.

(4543:12bb2876a62e). Without this, some third party applications
may break because the lack of AVL related symbols.
FreeBSD base system are not affected because the FreeBSD ZFS command
line tools were all linked against libavl and thus hide the underlying
issue.

illumos, rather than using "1.0" everywhere.
Some of the translators use D functions that are not present in version
1.0 (e.g. inet_ntoa()) which can result in libdtrace crashing when running
scripts that restrict themselves to version 1.0
(e.g. with "-x version=1.0").

FreeBSD ZFS port unlike OpenSolaris does not use device IDs, and does not
implement respective devid_*() fuctions. It is pointless to open devices
just to close them back immediately.

The thread pool is used by libzfs to implement parallel disk scanning.
Without this change our dummy wrapper made `zpool import ZZZ` command to
scan all disks sequentially from the single thread when searching for pools.
This change makes it use two threads per CPU, same as in OpenSolaris.
On system with 200 HDDs this change reduces ZFS pool import time from 35
to 22 seconds.

fail to attach to stripped binaries. With the _r_debug_postinit symbol,
dtrace(1) can now set a breakpoint in the victim process after it has
registered its DOF table(s) with the kernel. r_debug_state cannot be used
for this purpose since it is called before DOF is made available, in which
case dtrace(1) cannot create USDT probes before the program begins
execution.

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.

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.

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

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
internally set all the unnamed DIE's name to "__anon__".
