Yes, but that is exactly the problem. It's a compile time config option
(set to 40 by default, and kept that way in most distributions), which is
insufficient in the case of more than 40 disks (or 20 dual-pathed disks).
My patch was to make this a runtime configurable option that defaults to the
value of CONFIG_SD_EXTRA_DISKS, but which the user can override at module
load time.
Kurt Garloff of SuSE posted on Friday a set of patches targeted at 2.4.20pre
that extends this much further (see thread sd_many done right on
linux-kernel), and deletes CONFIG_SD_EXTRA_DISKS entirely, dynamically using
unassigned majors as needed. I'll follow that patch progress. If it
appears that won't make 2.4.x, then I'll see about submitting my simple
patch.
Thanks,
Matt
