Description from Matt Ahrens's bug report at Delphix:
Add a new zfs property, "redundant_metadata" which can have values
"all" or "most". The default will be "all", which is the current
behavior. Setting to "most" will cause us to only store 1 copy of
level-1 indirect blocks of user data files.
Additional notes:
The new man page section for this property states
"The exact behavior of which metadata blocks
are stored redundantly may change in future releases."
and:
"When set to most, ZFS stores an extra copy of most types of
metadata. This can improve performance of random writes,
because less metadata must be written."
The current implementation is as described above in Matt's blog.
It is controlled by a new global integer
"zfs_redundant_metadata_most_ditto_level", currently initialized
to 2. When "redundant_metadata" is set to "most", only indirect
blocks of the specified level and higher will have additional ditto
blocks created.

Prior to this patch, space_maps were preferred solely based on the
amount of free space left in each. Unfortunately, this heuristic didn't
contain any information about the make-up of that free space, which
meant we could keep preferring and loading a highly fragmented space map
that wouldn't actually have enough contiguous space to satisfy the
allocation; then unloading that space_map and repeating the process.
This change modifies the space_map's to store additional information
about the contiguous space in the space_map, so that we can use this
information to make a better decision about which space_map to load.
This requires reallocating all space_map objects to increase their
bonus buffer size sizes enough to fit the new metadata.
The above feature can be enabled via a new feature flag introduced by
this change: com.delphix:spacemap_histogram
In addition to the above, this patch allows the space_map block size to
be increase. Currently the block size is set to be 4K in size, which has
certain implications including the following:
* 4K sector devices will not see any compression benefit
* large space_maps require more metadata on-disk
* large space_maps require more time to load (typically random reads)
Now the space_map block size can adjust as needed up to the maximum size
set via the space_map_max_blksz variable.
A bug was fixed which resulted in potentially leaking an object when
removing a mirrored log device. The previous logic for vdev_remove() did
not deal with removing top-level vdevs that are interior vdevs (i.e.
mirror) correctly. The problem would occur when removing a mirrored log
device, and result in the DTL space map object being leaked; because
top-level vdevs don't have DTL space map objects associated with them.

usage on a new pool and snippet of the output it generates:
# zpool create tank /dev/vd{b,c,d}
# dd bs=1k if=/dev/urandom of=/tank/1kfile count=1
# dd bs=3k if=/dev/urandom of=/tank/3kfile count=1
# dd bs=64k if=/dev/urandom of=/tank/64kfile count=1
# zdb -bbbb tank

...
127: 0

The blocks are also broken down by their indirection level. Expanding on
the above example:
# zfs set recordsize=1k tank
# dd bs=1k if=/dev/urandom of=/tank/2x1kfile count=2
# zdb -bbbb tank
...

There's now a single 1K L1 block which is the indirect block needed for
the '2x1kfile' file just created, as well as two more 1K L0 blocks from
the same file.
This can be used to get a distribution of the block sizes used within
the pool, on a per object type basis.

If the smaller of 2 different sized child vdev's of a mirrored vdev is
detached, and the pool has the autoexpand property set to off, as the
remaining larger vdev is promoted to a top level vdev it fails to retain
the asize of the original top level mirror vdev and therefore partially
autoexpands.
This partially autoexpanded state leaves the new vdev too large to
re-mirror by adding the smaller vdev back in, and the pool fails to
utilize the space until next imported.
If the autoexpand property is set to on, the child vdev grows
in size after it has been promoted to a top level vdev as expected.
This commit causes the remaining child mirror to retain the asize of its
old parent mirror vdev if the autoexpand property is set to off,
this allows the smaller vdev to be re-added if required the vdev
can then be told to expand if required by the usual using zpool online -e.

There are two common locations where udev and dracut components are

targets check those common locations and pass them to rpmbuild. For
non-standard configurations these values can be provided by the
the following configure options:
--with-udevdir=DIR install udev helpers [default=check]
--with-udevruledir=DIR install udev rules [[UDEVDIR/rules.d]]
--with-dracutdir=DIR install dracut helpers [default=check]
When rebuilding using the source packages the per-distribution
default values specified in the spec file will be used. This is
the preferred way to build packages for a distribution but the
ability to override the defaults is provided as a convenience.

From day one the various ZFS libraries should have been placed in their
own sub-packages. Primarily this allows for multiple major versions of
the libraries to be concurrently installed. It also facilitates a
smaller build environment by minimizing the required dependencies.
The specific changes required to split the libraries from the utilities
are as follows:
* libzpool2, libnvpair1, libuutil1, and libzfs2 packages were added
and contain the versioned shared libraries. The Fedora packaging
guidelines discourage providing static libraries so they are not
included in the packages.
http://fedoraproject.org/wiki/Packaging:Guidelines#Packaging_Static_Libraries
* The zfs-devel package was renamed libzfs2-devel and the new package
obsoletes the old zfs-devel package. This package includes all
the required headers for the libzpool2, libnvpair1, libuutil1, and
libzfs2 libraries and their respective unversioned shared libraries.
This package should eventually be split in to individual lib*-devel
packages but it will still take some work to cleanly separate them.
Therefore the libzfs2-devel package provides the expected lib*-devel
packages so the all proper dependencies can still be created.
http://fedoraproject.org/wiki/Packaging:Guidelines#Devel_Packages
* Moved '/sbin/ldconfig' execution from the zfs packge to each of the
new library packages as described by the packaging guidelines.
http://fedoraproject.org/wiki/Packaging:Guidelines#Shared_Libraries
* The /usr/share/doc/ files were moved in to the libzfs2-devel package.
* Updated config/deb.am to be aware of the packaging changes. This
ensures that 'deb-utils' make target converts all the resulting
packages generated by the 'rpm-utils' target.

Issue: #2145
Clang's static analyzer reported that the value assigned to pcksum is
never used. That is because we initialize both zc and pcksum to {{ 0 }}
and then do `pcksum = zc;`. That is fairly pointless. However, it has
the effect of generating a false positive in Clang's static analyzer.
Since noise from false positives can obscure real issues, we fix it
anyway.

Issue #2330
Clang's static analyzer reported a memory leak in zpool_clear_label().
Upon review, it turns out to be right. This should be a very short lived
leak because no daemons use this functionality, but that does not
preclude the possibility of third party daemons that do use it. Lets fix
it to be a good Samaritan.

Issue #2330
Some kernel definitions were buried inside the #if... #endif logic for
ACLs. When ACLs are not available these definitions get lost causing
the build to fail.

Closes#2349
Running 'yum upgrade zfs-dkms' package could appear to work properly
and still leave you with no zfs modules installed. This will occur
when only the zfs release, and not the version, are incremented.
This may be the case for a fast moving zfs-testing repository.
During the upgrade process DKMS will realize that zfs-x.y.z is already
installed and remove it. DKMS then correctly builds the new modules
for zfs-x.y.z. However, as a final step when the old zfs-x.y.z-r is
removed the %preun script runs and removes the newly build modules.
To handle this case the %preun script has been updated to only run
when the installed version exactly matches the full spec file version.
This change also updated ChangeLog section based on the DKMS
reference spec file.
