The function that fills the uberblock ring buffer on every device label
has been reworked to avoid occasional failures caused by a race
condition that prevents 'zpool sync' from writing some uberblock
sequentially: this happens when the pool sync ioctl dispatch code calls
txg_wait_synced() while we're already waiting for a TXG to sync.

The only place vn_rename and vn_remove are used is when writing
out an updated pool configuration file. By truncating the file
instead of renaming and removing it we can avoid having to implement
these interfaces entirely. Functionally an empty cache file is
treated the same as a missing cache file. This is particularly
advantageous because the Linux kernel has never provided a way
to reliably implement vn_rename and vn_remove.
The cachefile_004_pos.ksh test case was updated to understand
that an empty cache file is the same as a missing one.
The zfs-import-* systemd service files were not updated to use
ConditionFileNotEmpty in place of ConditionPathExists. This
means that after exporting all pools and rebooting new pools
will not the scanned for on the next boot. This small change
should not impact normal usage since pools are not exported
as part of a normal shutdown.
Documentation was updated accordingly.

Inspection of a Ubuntu 14.04 x64 system revealed that the config file
used to build the kernel image differs from the config file used to
build kernel modules by the presence of CONFIG_DEBUG_INFO=y:
This in itself is insufficient to show that the kernel is built with
debuginfo, but a cursory analysis of the debuginfo provided and the
size of the kernel strongly suggests that it was built with
CONFIG_DEBUG_INFO=y while the modules were not. Installing
linux-image-$(uname -r)-dbgsym had no obvious effect on the debuginfo
provided by either the modules or the kernel.
The consequence is that issue reports from distributions such as Ubuntu
and its derivatives build kernel modules without debuginfo contain
nonsensical backtraces. It is therefore desireable to force generation
of debuginfo, so we implement --enable-debuginfo. Since the build system
can build both userspace components and kernel modules, the generic
--enable-debuginfo option will force debuginfo for both. However, it
also supports --enable-debuginfo=kernel and --enable-debuginfo=user for
finer grained control.
Enabling debuginfo for the kernel modules works by injecting
CONFIG_DEBUG_INFO=y into the make environment. This is enables
generation of debuginfo by the kernel build systems on all Linux
kernels, but the build environment is slightly different int hat
CONFIG_DEBUG_INFO has not been in the CPP. Adding -DCONFIG_DEBUG_INFO
would fix that, but it would also cause build failures on kernels where
CONFIG_DEBUG_INFO=y is already set. That would complicate its use in
DKMS environments that support a range of kernels and is therefore
undesireable. We could write a compatibility shim to enable
CONFIG_DEBUG_INFO only when it is explicitly disabled, but we forgo
doing that because it is unnecessary. Nothing in ZoL or the kernel uses
CONFIG_DEBUG_INFO in the CPP at this time and that is unlikely to
change.
Enabling debuginfo for the userspace components is done by injecting -g
into CPPFLAGS. This is not necessary because the build system honors the
environment's CPPFLAGS by appending them to the actual CPPFLAGS used,
but it is supported for consistency.

In ZFSOnLinux, our sources and build system are self contained such that
we do not need to make changes to the Linux kernel sources. Reiser4 on
the other hand exists solely as a kernel tree patch and opts to make
changes to the kernel rather than adapt to it. After Linux 4.1 made a
VFS change that replaced new_sync_read with do_sync_read, Reiser4's
maintainer decided to modify the kernel VFS to export the old function.
This caused our autotools check to misidentify the kernel API as
predating Linux 4.1 on kernels that have been patched with Reiser4
support, which breaks our build.
Reiser4 really should be patched to stop doing this, but lets modify our
check to be more strict to help the affected users of both filesystems.
Also, we were not checking the types of arguments and return value of
new_sync_read() and new_sync_write() . Lets fix that too.

When the compressed ARC feature was added in commit d3c2ae1
the method of reference counting in the ARC was modified. As
part of this accounting change the arc_buf_add_ref() function
was removed entirely.
This would have be fine but the arc_buf_add_ref() function
served a second undocumented purpose of updating the ARC access
information when taking a hold on a dbuf. Without this logic
in place a cached dbuf would not migrate its associated
arc_buf_hdr_t to the MFU list. This would negatively impact
the ARC hit rate, particularly on systems with a small ARC.
This change reinstates the missing call to arc_access() from
dbuf_hold() by implementing a new arc_buf_access() function.

When the multihost property is enabled it should be impossible to
import an active pool even using the force (-f) option. This patch
prevents a forced import from succeeding when importing with a

The root cause of the problem is that the kernel modules trusted
the hostid provided in configuration. This is always correct when
the configuration is generated by scanning for the pool. However,
when using an existing cache file the hostid could be stale which
would result in the activity check being skipped.
Resolve the issue by always using the hostid read from the label
