3.19.8-ckt18 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------ From: "Yan, Zheng" <[email protected]> commit 1f041a89b4f22cf2e701514f4b8f73a8b1e06a3e upstream. struct timespec uses 'long' to present second and nanosecond. 'long' is 64 bits on 64bits machine. ceph MDS expects time stamp to be encoded as struct ceph_timespec, which uses 'u32' to present second and nanosecond.
