Dear listmembers,
referring to my own question (and to Jeff Mahoneys email), would it be sufficient to simply change
- --- linux-2.6.17/fs/partitions/sun.c 2006-01-02 22:21:10.000000000 -0500
+++ linux-2.6.17.fix/fs/partitions/sun.c 2006-08-26 11:54:54.000000000 -0400
@@ -74,10 +74,10 @@ int sun_partition(struct parsed_partitio
spc = be16_to_cpu(label->ntrks) * be16_to_cpu(label->nsect);
for (i = 0; i < 8; i++, p++) {
unsigned long st_sector;
- - int num_sectors;
+ unsigned int num_sectors;
st_sector = be32_to_cpu(p->start_cylinder) * spc;
num_sectors = be32_to_cpu(p->num_sectors);
in order to get rid of the meaningless negative numbers? If possible this would be highly preferrable over a solution that renders this partition useless. If Sun Os cannot handle this, maybe an error message when configuring such a disk would be helpful.
Once again, thank you for your feedback,
best regards
Dieter Jurzitza
