| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long.

* 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

| | | | | | | | | | | | | | | | (1) The reads are always done from the first n/2 disks. (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.
