Fixed with "rbd: don't treat CEPH_OSD_OP_DELETE as extent op". I rebased it into testing before "libceph: add CREATE osd operation support" (which is what triggered this) to keep us bisectable.

For the record, since the stack trace doesn't explain anything, this was the following BUG_ON in osd_req_op_extent_init():

BUG_ON(opcode != CEPH_OSD_OP_READ && opcode != CEPH_OSD_OP_WRITE &&
       opcode != CEPH_OSD_OP_ZERO && opcode != CEPH_OSD_OP_TRUNCATE);
