Title:
POSIX fix for ftrace test in ubuntu_kernel_selftests
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Disco:
In Progress
Status in linux source package in Eoan:
In Progress
Bug description:
== Justification ==
There are some non-POSIX implementations in the test script, which will
generate some noise in the test reports like:
-e -n [1] Basic trace file check
-e [PASS]
-e -n [2] Basic test for tracers
-e [PASS]
== Fix ==
* 4ce55a9c (selftests/ftrace: Replace \e with \033)
* 37fb665b (selftests/ftrace: Replace echo -e with printf)
These two patches can be cherry-picked into D/E
== Test ==
Tested on a P8 box with Disco, the patched test will print the report in a
proper format:
[1] Basic trace file check [PASS]
[2] Basic test for tracers [PASS]
== Regression Potential ==
No regression is expected. This patchset just make sure this test comply with
POSIX standard.
