From 4ce5726c0ed93e7607c5076f587546c32cf83c2f Mon Sep 17 00:00:00 2001 From: Nate Clark Date: Wed, 4 Jan 2017 15:24:22 -0500 Subject: [PATCH 150/152] libblkid/minix: Match minix superblock types All of the types in the minix super block are unsigned but in probe_minix they were being treated as signed. This would cause some of the extra sanity checks to pass on a non minix device. The types were updated to match the return types of the helper functions in disk-utils/minix_programs.h This can be checked by creating a swap partition with one of these UUIDs 35f1f264-2468-471a-bc85-acc9f4bc04a3 35f1f264-6824-471a-bc85-acc9f4bc04a3 35f1f264-2478-471a-bc85-acc9f4bc04a3 35f1f264-7824-471a-bc85-acc9f4bc04a3 Prior to this change they would all be considered minix and swap by blkid.
