chuck 718ac5d246 [import changes from sparc port]
- moved disk_busy() call from xdstrategy() to xdc_startbuf()
        [prevents disk_unbusy panic when disk is loaded (if no
        free IOPBs, xdstrategy() would queue the buffer for pickup
        by xdcintr() but xdcintr() would never call disk_busy().
        xdc_startbuf() is a better place since all bufs are routed
        through here]   problem detected by girish@dworkin.wustl.edu,
        diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
        XDC_FREE() [don't want to access a data structure that was just put
        on a free list]

chuck 8f339409b7 sync with sparc:
- move disk_attach() to before reading the disk label as per Jason.
	otherwise we are reading into an unallocated buffer (oops!)
1996-01-13 03:50:05 +00:00
thorpej 5b39541e48 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.
