Something like this:
[acme@jouet perf]$ cat /proc/kallsyms | head (null) A irq_stack_union (null) A __per_cpu_start (null) A cpu_debug_store (null) A cpu_tss_rw (null) A gdt_page (null) A exception_stacks (null) A entry_stack_storage (null) A espfix_waddr (null) A espfix_stack (null) A cpu_llc_id [acme@jouet perf]$ id uid=1000(acme) gid=1000(acme) groups=1000(acme),10(wheel),18(dialout),54(lock) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 [acme@jouet perf]$
