Oh ,Sorry,
To build ceph.ko
need "cp libceph/Module.symvers ceph/ "
but ,i detected a OOPS ,ceph-client-standalone.git + ceph 0.23
reproduce steps:
/ceph-client-standalone$ make -C libceph/
/ceph-client-standalone$ cp libceph/Module.symvers ./ceph/
/ceph-client-standalone$ make -C ceph/
/ceph-client-standalone$ sudo insmod libceph/libceph.ko
/ceph-client-standalone$ sudo insmod ceph/ceph.ko
/ceph-client-standalone$ sudo mount.ceph 172.16.10.171:6789:/ /mnt/ceph
killed
