From 1f041a89b4f22cf2e701514f4b8f73a8b1e06a3e Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Tue, 13 Jan 2015 15:20:52 +0800 Subject: [PATCH] ceph: fix request time stamp encoding 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.
