You've enabled CONFIG_BASE_SMALL and so the major_names[] hashtable has just one element. device-mapper uses dynamic major allocation, the range of which is limited to the size of the top-level major_names[] array. You ran out of slots and register_blkdev() failed. So for now I guess we must drop base-small-shrink-major_names-hash.patch. Al, that code looks rather crappy. Shouldn't we be using an idr tree or something? Also, we can never generate a major number of zero if the caller passed in major=0. How come? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
