-Subject: [PATCH] libblkid: zeroize errno on blkid_probe_get_buffer() success
-
-Since 37f4060225df0591ab8e1dd676dbc8115d900d4f prober functions are
-sensitive to errno, it seems more robust to set errno=0 with in
-blkid_probe_get_buffer() on success than set the zero on all places
-where we call blkid_probe_get_buffer().

+Subject: [PATCH] include sysmacros.h where used
+
+BSD/Linux systems stick major/minor/makedev in sysmacros.h.  Newer Linux
+libraries have been moving away from including sysmacros.h implicitly via
+sys/types.h, so include it directly.
