Applied to groovy/master-next, thanks!
From: Colin Ian King <colin.king@canonical.com> BugLink: https://bugs.launchpad.net/bugs/1891528 A couple of ftrace kernel self test regression tests are failing on systems with 1 CPU, notably small 1 CPU cloud instances. The two tests that are failing are: [20] ftrace - function graph filters with stack tracer [21] ftrace - function graph filters Bisected this down to commit 717e3f5ebc82 ("ftrace: Make function trace pid filtering a bit more exact") in linux 5.6-rc4 and found and tested an upstream fix to this issue with the commit c58b6b0372de ("ftrace: Fix ftrace_trace_task return value").
