This part can still cause a failure in one of test cases in my cpuset
partition test script. In this particular case, the CPU to be
offlined is an
isolated CPU with scheduling disabled. As a result, total_bw is 0
and the
__dl_overflow() test failed. Is there a way to skip the
__dl_overflow() test
for isolated CPUs? Can we use a null total_bw as a proxy for that?
Can you please share the repro script? Would like to check locally what
is going on.
Just run tools/testing/selftests/cgroup/test_cpuset_prs.sh.
The failing test is
# Remote partition offline tests
" C0-3:S+ C1-3:S+ C2-3 . X2-3 X2-3 X2-3:P2:O2=0 . 0
A1:0-1,A2:1,A3:3 A1:P0,A3:P2 2-3"
You can remove all the previous lines in the TEST_MATRIX to get to
failed test case immediately eliminating unnecessary noise in your testing.
