This is\nthen used in __bpf_get_stack() to check for user mode, resulting in a\nkernel oops. Guard against this by checking return value of\ntask_pt_regs() before trying to obtain the call chain."

Luego, esto se usa en __bpf_get_stack() para verificar el modo de usuario, lo que genera un kernel ups.
