. add receive hooks in the kernel to print asynchronously delivered messages . do not rely on MF_REPLY_PEND to decide between calls and errors, as that isn't reliable for asynchronous messages; try both instead . add _sendcall() that extract-mfield.sh can then reliably recognize the fields for messages that are sent with just send() . add DEBUG_DUMPIPC_NAMES to restrict printed messages to from/to given process names Change-Id: Ia65eb02a69a2b58e73bf9f009987be06dda774a3
