this also changes the mirror striping strategy a bit to achieve the scatter-gathering; of course it has been proven that new discipline still makes troubles thus not enabling it yet );

really useful as a performance booster. The interleave needs to be a
multiple of the software page size (CLBYTES) and not have mirror components
if the new optimized policy should be used, otherwise the old policy will
be used still.

New generic disk framework. Highlights:
New metrics handling. Metrics are now kept in the new `struct disk'.
Busy time is now stored as a timeval, and transfer count in bytes.
Storage for disklabels is now dynamically allocated, so that the size
of the disk structure is not machine-dependent.
Several new functions for attaching and detaching disks, and handling
metrics calculation.
Old-style instrumentation is still supported in drivers that did it
before. However, old-style instrumentation is being deprecated, and
will go away once the userland utilities are updated for the new
framework.
For usage and architectural details, see the forthcoming disk(9)
manual page.
