description |
ftrace kernel self test regression tests are failing on instances with 1 CPU. One set of failures are because of a regression caused by commit 717e3f5ebc82 ("ftrace: Make function trace pid filtering a bit more exact")
The fix is upstream commit:
commit c58b6b0372de0d4cd0536d6585addd1b36b151ae

ftrace: Fix ftrace_trace_task return value |
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"). |
