Subject: [PATCH 3.12 115/170] tools: ffs-test: fix header values endianess

From: Michal Nazarewicz <mina86@...a86.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit f35f71244da6e51db4e1f2c7e318581f498ececf upstream.

It appears that no one ever run ffs-test on a big-endian machine,
since it used cpu-endianess for fs_count and hs_count fields which
should be in little-endian format.  Fix by wrapping the numbers in
cpu_to_le32.
