The flow dissector test currently relies on generic CHECK macros to perform tests. Update those to newer, more-specific ASSERT macros. This update allows to get rid of the global duration variable, which was needed by the CHECK macros Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com> --- .../selftests/bpf/prog_tests/flow_dissector.c | 41 +++++++++++----------- 1 file changed, 21 insertions(+), 20 deletions(-)
