Then, I ran the linux-mm testsuite (lots of hard-coded places because I only need to run this on RHEL8) first: # git clone https://gitlab.com/cailca/linux-mm # cd linux-mm; make # ./random -k Then, run the whole LTP syscalls: # ./runltp -f syscalls If that is still not triggered, it needs some syscall fuzzing: # ./random -x 0-100 -f
