Subject: function_graph selftest fails with !DYNAMIC
Date: Wed, 2 Nov 2011 20:32:55 +0530
Message-ID: <20111102150255.GA6973@debian> (raw)

The function_graph selftest fails when CONFIG_DYNAMIC_FTRACE is not set
(tested on x86-64) on current kernels:

[    0.300124] Testing tracer function: PASSED
[    0.446092] Testing tracer function_graph: .. no entries found ..FAILED!

2b499381bc50ede01b3d8eab164ca2fad00655f0 is the first bad commit
commit 2b499381bc50ede01b3d8eab164ca2fad00655f0
Author: Steven Rostedt <srostedt@redhat.com>

    ftrace: Have global_ops store the functions that are to be traced
    
    This is a step towards each ops structure defining its own set
    of functions to trace. As the current code with pid's and such
    are specific to the global_ops, it is restructured to be used
    with the global ops.
