One off the cause is because vmap function is not paired to relative
fuctions with
vunmap function wich result memory leaks.
Offcourse is and another cause.
Follow example on map_irq_stack function have vmap but not have guard
when this function fail, at the end of fuction address is on

per_cpu(pcpu_hot.hardirq_stack_ptr, cpu) and result if you wish you can use
vunmap(per_cpu(pcpu_hot.hardirq_stack_ptr, cpu));
