* There is no such thing any more as "struct bdevsw".Julian Elischer1998-07-041-8/+22
| | | | | | | | | | | | | | | | | | | | | 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.

* This commit fixes various 64bit portability problems required forDoug Rabson1998-06-071-2/+2
| | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=36735

* Change how mirror writes are handled, according to the discussion on theSatoshi Asami1996-03-261-9/+39
| | | | | | | | | | | | | | | | | | | | | mailing list. When initiating a write, ccdbuffer() returns two "struct ccdbuf *"s linked together by the cb_mirror field. "cb_pflags & CCDPF_MIRROR_DONE" is set to 0 on both of them. When a component returns to ccdiodone(), it checks if "cb_pflags & CCDPF_MIRROR_DONE" is set or not. If not, it sets the partner's flag and returns. If it is, it means its partner has already returned, so it will go to the regular cleanup (which is in the fallthrough code). There should be no performance or functionality changes unless the higher-level scsi driver does something with the resid value. The change is purely aesthetical and prepares us for the parity implementation. Notes: svn path=/head/; revision=14821

(2) Each write is done twice, to the "data" disk (in the first half) and the "mirror" disk (in the second half). ccdbuffer() now takes an extra argument (struct ccdbuf **) and stores the pointer to ccdbuf in there. In case of a mirrored write, it allocates and stores two pointers. The "residual" is also doubled for mirrored writes so that ccdiodone() can correctly tell when all the writes are done.
