initialize all the data. This is huge waste of time and resources if
there were no writes yet, as there is no real data to synchronize.
Optimize this by sending "virgin" argument to secondary, which gives it a hint
that synchronization is not needed.
In the common case (where noth nodes are configured at the same time) instead
of synchronizing everything, we don't synchronize at all.

This is how ksh93 treats ! within a pipeline and makes the ! in
a | ! b | c
negate the exit status of the pipeline, as if it were
a | { ! b | c; }
Side effect: something like
f() ! a
is now a syntax error, because a function definition takes a command,
not a pipeline.

existing code caused problems with some SCSI controllers.
A new sysctl kern.cam.ada.spindown_shutdown has been added that controls
whether or not to spin-down disks when shutting down.
Spinning down the disks unloads/parks the heads - this is
much better than removing power when the disk is still
spinning because otherwise an Emergency Unload occurs which may cause damage
to the actuator.

to use the generic hash32_buf() function. Although adding the
bytes seemed sufficient for UFS and ZFS, since most of the bytes
are the same for file handles on the same volume, this might not
be sufficient for other file systems. Use of a generic function
also seems preferable to one specific to NFSv4.

the association notification), the included information though always
contains an elem block with an odd number of bytes. We handle the last
byte as if it might contain a whole elem block, this of course is not
true as one byte is not enough to hold a block, we therefore discard the
complete frame. The solution here is to subtract one from the actual
notification length, this is also what the Linux driver does. With this
change the frames ends exactly where the last elem block ends.

With r169630 I disabled symbol versioning because it broke rtld. With
r211706 rtld got broken for ia64 & powerpc64. It was fixed for powerpc64
with r212497. In between, r211749 removed the exports table because the
version script handled the exports. But wait, symbol versioning was
disabled on ia64.
With exports controlled by the version script and symbol versioning
disabled, all symbols are exported and too many symbols bind to the
definition in rtld. Let's just say that waird things happen.
So, enable symbol versioning on ia64 and apply a work-around for the
SIGSEGV that triggered r169630 to begin with: when rtld relocates
itself, it comes across r_debug_state and for some reason can't find the
definition. This causes a failure, relocation aborts and null pointers
galore. The work-around is to ignore the missing definition when rtld
is relocating itself and keep going.
Maybe with the next binutils this will all go away. Maybe not, in
which case I still need to figure out why r_debug_state cannot be found.
BTW: r_debug_state is in the symbol map -- I don't think any other rtld
symbols that rtld references are in the symbol map...
