The following patch fixes a bug in the processing of the sb= (alternate superblock) mount option for ext2: for devices with 1024-byte blocks, the value from the option is never actually used. This patch is for kernel 2.4.25. 2.6.5 also has an issue with sb=, and I'll send a patch for that separately.
