+Subject: md: fix super_offset endianness in super_1_rdev_size_change
+
+From: Jason Yan <yanaijie@huawei.com>
+
+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.
