Would it make sense to just reuse kernel/bpf/percpu_freelist.c for kretprobes?
Thanks for the info. bpf/percpu_freelist does meet the requirements of kretprobe_instances management and is more compact in memory. But the spinlock usage (through locally) looks a bit heavy since it must disable interrupts on local cpu.
I will perform a test to collect some data for comparison.
