The add_remove_fprobe_module test checks the number of functions added to the enabled_functions file to make sure that the functions added or removed is as expected. The issue is that it expects this file to be empty on start up. Now that systemd uses BPF that attaches to functions via ftrace, this file is not empty in several systems: # cat /sys/kernel/tracing/enabled_functions bpf_lsm_file_open (1) R D M tramp: ftrace_regs_caller+0x0/0x61 (call_direct_funcs+0x0/0x50) direct(jmp)-->bpf_trampoline_6442529439+0x0/0xe9 Change the test to read the number of lines in enabled_functions at the start of the test and subtract that from the value of the count for the checks within the test.
