Subject: [PATCH 174/176] libblkid/minix: Match minix superblock types
e42290
e42290
All of the types in the minix super block are unsigned but in
e42290
probe_minix they were being treated as signed. This would cause some of
e42290
the extra sanity checks to pass on a non minix device. The types were
e42290
updated to match the return types of the helper functions in
e42290
disk-utils/minix_programs.h
e42290
e42290
This can be checked by creating a swap partition with one of these UUIDs

e42290
Prior to this change they would all be considered minix and swap by
e42290
blkid.
