- 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.
