Are CAP_SYS_ADMIN and CAP_SYS_NICE still needed for SQPOLL?

[Stefano Garzarella]

Hi Jens, Hi Pavel,
I was taking a look at the new SQPOLL handling with io_thread instead of 
kthread. Great job! Really nice feature that maybe can be reused also in 
other scenarios (e.g. vhost).

Regarding SQPOLL, IIUC these new threads are much closer to user 
threads, so is there still a need to require CAP_SYS_ADMIN and 
CAP_SYS_NICE to enable SQPOLL?

Thanks,
Stefano
