[PATCH] Make xentrace hypercall a bit more sane
xentrace, setsize and the hypervisor don''t seem to be on the same page. If tracing is not enabled, the hypercall will only allow TBUF_SET_SIZE and TBUF_ENABLE. However, set_size calls TBUF_GET_INFO, and xentrace wants to call TBUF_SET_EVT_MASK and TBUF_SET_CPU_MASK before calling TBUF_ENABLE. I don''t see any reason not to call SET_*_MASK and GET_INFO if tracing is not enabled. If the buffer hasn''t been allocated yet, GET_INFO should just return something invalid in the mfn field. Anyone calling should check this value. Comments? -Geor...
