From 8e8d7f13b6d5a93b3d2cf9a4ceaaf923809fd5ac Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 5 Jan 2017 10:38:34 +0000 Subject: afs: Add some tracepoints Add three tracepoints to the AFS filesystem: (1) The afs_recv_data tracepoint logs data segments that are extracted from the data received from the peer through afs_extract_data(). (2) The afs_notify_call tracepoint logs notification from AF_RXRPC of data coming in to an asynchronous call. (3) The afs_cb_call tracepoint logs incoming calls that have had their operation ID extracted and mapped into a supported cache manager service call. To make (3) work, the name strings in the afs_call_type struct objects have to be annotated with __tracepoint_string. This is done with the CM_NAME() macro. Further, the AFS call state enum needs a name so that it can be used to declare parameter types.
