Kernel: 2.4.33
Issue: really fix size display for sun partitions larger than 1TByte
Signed off by: Dieter Jurzitza DJurzitza@xxxxxxxxxxxxxxxx
Problem: the last fix introduced by Jeff Mahoney for kernel 2.6 was not complete for kernel 2.4 (as applied)
I found out that add_gd_partition is called by any type of partition (2.4). add_gd_partition is defined as add_gd_partition (int, int), what makes no sense to me as negative numbers should never occur here. As long as add_gd_partition is not changed to add_gd_partition (unsigned, unsigned), /proc/partitions will keep showing negative numbers.
If ever someone could look into this, within the different partition type files in linux/fs/partitions the parameters to add_gd_partitions seem to be chosen arbitrarily between int, unsigned and unsigned long, whatever seemed to be appropriate, I think it would make sense to get consistent parameters to add_gd_partition from all partition types here.
Especially if one takes into account that sizeof (long) and sizeof (int) may differ significantly i. e. on sparc.
Take care
