When building from an arbitrary commit in the git tree it's useful
for the resulting packages to be uniquely identifiable. Therefore,
the build system has been updated to detect if your compiling in
git tree.
If you are building in a git tree, and there are commits after the
last annotated tag. Then the <id>-<hash> component of 'git describe'
will be used to overwrite the 'Release:' field in the META file.
The only tricky part is that to ensure the 'make dist' tarball is
built using the correct release. A dist-hook was added to the top
level make file to rewrite the META file using the correct release.

Calling cond_resched() after each object is freed and then after each

Adding the 'spl-dkms = VERSION' dependency to the zfs-dkms
package ensures the spl will be installed before zfs. This
cleanly handles the initial 'yum localinstall' case.
However, this does not address the dkms rebuilds caused by
a new kernel being installed. For that we still rely on the
clunky --with-spl-timeout=<timeout> configure option which
allows the zfs compilation to be briefly delayed while the

The assumption in zio_ddt_free() is that ddt_phys_select() must
always find a match. However, if that fails due to a damaged
DDT or some other reason the code will NULL dereference in
ddt_phys_decref().
While this should never happen it has been observed on various
platforms. The result is that unless your willing to patch the
ZFS code the pool is inaccessible. Therefore, we're choosing
to more gracefully handle this case rather than leave it fatal.

Because the install location for the spl/zfs-devel headers was
changed we need to refresh the auto-detect code. Note that
for packaging which already explicitly calls --with-spl{-obj}
nothing has changed.
The updated code is now structured like that in ZFS_AC_KERNEL
and should be cleaner and easier to maintain. In addition,
it's stricter about detecting a valid source and object
directory. It requires:
* The source directory contains the file 'spl.release'
* The object directory contains the file 'spl_config.h'
* The following paths will be checked. Notice the /var/lib/
and /usr/src paths require that the spl and zfs version be
matched. This is done to prevent accidentally mixing releases.
dnl # 1) /var/lib/dkms/spl/<version>/build
dnl # 2) /usr/src/spl-<version>/<kernel-version>
dnl # 3) /usr/src/spl-<version>

The new snapdev dataset property may be set to control the
visibility of zvol snapshot devices. By default this value
is set to 'hidden' which will prevent zvol snapshots from
appearing under /dev/zvol/ and /dev/<dataset>/. When set to
'visible' all zvol snapshots for the dataset will be visible.
This functionality was largely added because when automatic
snapshoting is enabled large numbers of read-only zvol snapshots
will be created. When creating these devices the kernel will
attempt to read their partition tables, and blkid will attempt
to identify any filesystems on those partitions. This leads
to a variety of issues:
1) The zvol partition tables will be read in the context of
the `modprobe zfs` for automatically imported pools. This
is undesirable and should be done asynchronously, but for
now reducing the number of visible devices helps.
2) Udev expects to be able to complete its work for a new
block devices fairly quickly. When many zvol devices are
added at the same time this is no longer be true. It can
lead to udev timeouts and missing /dev/zvol links.
3) Simply having lots of devices in /dev/ can be aukward from
a management standpoint. Hidding the devices your unlikely
to ever use helps with this. Any snapshot device which is
needed can be made visible by changing the snapdev property.
NOTE: This patch changes the default behavior for zvols which
was effectively 'snapdev=visible'.
