phk 156695e286 Create a general facility for making dev_t's depend on another ... dev_t. The dev_depends(dev_t, dev_t) function is for tying them to each other. When destroy_dev() is called on a dev_t, all dev_t's depending on it will also be destroyed (depth first order). Rewrite the make_dev_alias() to use this dependency facility. kern/subr_disk.c: Make the disk mini-layer use dependencies to make sure all relevant dev_t's are removed when the disk disappears. Make the disk mini-layer precreate some magic sub devices which the disk/slice/label code expects to be there. kern/subr_disklabel.c: Remove some now unneeded variables. kern/subr_diskmbr.c: Remove some ancient, commented out code. kern/subr_diskslice.c: Minor cleanup. Use name from dev_t instead of dsname()		2001-05-26 08:27:58 +00:00
