libceph: allow STAT osd operations
Add support for CEPH_OSD_OP_STAT operations in the osd client and in rbd. This operation sends no data to the osd; everything required is encoded in identity of the target object. The result will be ENOENT if the object doesn't exist. If it does exist and no other error occurs the server returns the size and last modification time of the target object as output data (in little endian format). The size is a 64 bit unsigned and the time is ceph_timespec structure (two unsigned 32-bit integers, representing a seconds and nanoseconds value). This resolves: http://tracker.ceph.com/issues/4007 Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
