4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jason Yan <yanaijie@xxxxxxxxxx> commit 3fb632e40d7667d8bedfabc28850ac06d5493f54 upstream. The sb->super_offset should be big-endian, but the rdev->sb_start is in host byte order, so fix this by adding cpu_to_le64.
