Yan, Zheng 717e6f2893 ceph: avoid panic in create_session_open_msg() if utsname() returns NULL ... utsname() can return NULL while process is exiting. Kernel releases file locks during process exits. We send request to mds when releasing file lock. So it's possible that we open mds session while process is exiting. utsname() is called in create_session_open_msg().
