+Subject: partitions/msdos: Unable to mount UFS 44bsd partitions
+
+From: Richard Narron <comet.berkeley@gmail.com>
+
+commit 5f15684bd5e5ef39d4337988864fec8012471dda upstream.
+
+UFS partitions from newer versions of FreeBSD 10 and 11 use relative
+addressing for their subpartitions. But older versions of FreeBSD still
+use absolute addressing just like OpenBSD and NetBSD.
+
+Instead of simply testing for a FreeBSD partition, the code needs to
+also test if the starting offset of the C subpartition is zero.
