From 025db80c9e421efef11f2b83b7f78a11476f06db Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 2 Nov 2017 15:27:51 +0000 Subject: afs: Trace the initiation and completion of client calls Add tracepoints to trace the initiation and completion of client calls within the kafs filesystem. The afs_make_vl_call tracepoint watches calls to the volume location database server. The afs_make_fs_call tracepoint watches calls to the file server. The afs_call_done tracepoint watches for call completion.
