Subject: [PATCH 3.10 104/129] ceph: cleanup types in striped_read()

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

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 688bac461ba3e9d221a879ab40b687f5d7b5b19c upstream.

We pass in a u64 value for "len" and then immediately truncate away the
upper 32 bits.
