3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard <richard@aaazen.com>
commit 223220356d5ebc05ead9a8d697abb0c0a906fc81 upstream.
The code in block/partitions/msdos.c recognizes FreeBSD, OpenBSD and NetBSD partitions and does a reasonable job picking out OpenBSD and NetBSD UFS subpartitions.
But for FreeBSD the subpartitions are always "bad".
Kernel: <bsd:bad subpartition - ignored
Though all 3 of these BSD systems use UFS as a file system, only FreeBSD uses relative start addresses in the subpartition declarations.
The following patch fixes this for FreeBSD partitions and leaves the code for OpenBSD and NetBSD intact:
