[PATCH] selftests/ftrace: Fix check of return value in fgraph-retval.tc test

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Steven Rostedt <rostedt@xxxxxxxxxxx>

The addition of recording both the function name and return address to the
function graph tracer updated the selftest to check for "=-5" from "= -5".
But this causes the test to fail on certain configs, as "= -5" is still a
value that can be returned if function addresses are not enabled (older kernels).

Check for both "=-5" and " -5" as a success value.

Fixes: 21e92806d39c6 ("function_graph: Support recording and printing the function return address")

Shuah, this update is only for changes in my tree, so you do not need to add it.
