Title:
ubuntu_kernel_selftests.ftrace:ftracetest fails with bionic:linux
4.15.0-168.176 on s390x
Status in ubuntu-kernel-tests:
New
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Bionic:
Fix Released
Bug description:
SRU Justification
[Impact]
There seems to have been a typo in Commit 85bf17b28f97
("recordmcount.pl: look for jgnop instruction as well as bcrl on s390")
that causes errors in finding mcount locations. This seems to cause problems
with ftrace initialization leading to not being able to use ftrace
functions.
[Fix]
Fix the typo by changing it to the correct instruction.
[Test Case]
Ftrace files in /sys/kernel/debug/tracing should be able to be read
from and written to with normal functionality. Ftrace selftests should
now pass.
[Where things could go wrong]
Its a simple typo fix so none really.

==========================================================================
After some debugging I've found out that the testcases are not
actually run, the failure happens while running
'tools/testing/selftests/ftrace/test.d/functions:initialize_ftrace()',
on the following line:
[ -f set_ftrace_filter ] && echo | tee set_ftrace_*
After a reboot for clean ftrace state, with kernel 4.15.0-168-generic:
root@kleber-bionic:/sys/kernel/debug/tracing# head set_ftrace_*
