another resend of the partition patch for
ibm.c. Nobody sent a veto so far so please add it.
I suspect Linus wants it fixed "right", as we promised. I made the kludge with genhd_dasd_ioctl because Red Hat need to ship _something_ working while passing Viro approval. I never intended it to be applied to 2.5.
Remember that what Al did first _almost_ worked. The recursion happened because the SCSI code was so insanely convoluted, and only for SCSI removables. Perhaps it may be doable to fix that instead. Also I am thinking about special-casing the minor 0 and make it open without partition probing; then the probing happens on top of pre-opened minor 0 and spawns other minors. That should be good and proper.
The bad part is that the real fix for old broken ibm.c partitioning is now a hostage of resolution of ioctl-during-partitioning problem. I see no easy way to resolve it, it has to wait. Good thing my Hercules uses FBAs :)
