Add a prioritization field to the devstat_add_entry() call so that peripheral drivers can determine where in the devstat(9) list they are inserted. This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and any ports that depend on the devstat code, since the size of the devstat structure has changed. The devstat version number has been incremented as well to reflect the change.

Update system to new device statistics code.

Make struct buf->b_offset reflect the real byte offset which got

in via the uio struct. This enables device drivers to use != DEV_BSIZE blocking on devices with wierd sector/block sizes (ie CDROM's).

There is no such thing any more as "struct bdevsw".

There is only cdevsw (which should be renamed in a later edit to deventry or something). cdevsw contains the union of what were in both bdevsw an cdevsw entries. The bdevsw[] table stiff exists and is a second pointer to the cdevsw entry of the device. it's major is in d_bmaj rather than d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw). rawread()/rawwrite() went away as part of this though it's not strictly the same patch, just that it involves all the same lines in the drivers. cdroms no longer have write() entries (they did have rawwrite (?)). tapes no longer have support for bdev operations.

FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.
