3.19.8-ckt11 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 777d738a5e58ba3b6f3932ab1543ce93703f4873 upstream.
create_request_message() computes the maximum length of a message,
but uses the wrong type for the time stamp: sizeof(struct timespec)
may be 8 or 16 depending on the architecture, while sizeof(struct
ceph_timespec) is always 8, and that is what gets put into the
message.
Found while auditing the uses of timespec for y2038 problems.
Fixes: b8e69066d8af ("ceph: include time stamp in every MDS request")
