Re: [PATCH v4 5/6] add listmount(2) syscall

Why use struct __mount_arg (or struct mnt_id_req :) here rather than
just passing in the mount ID directly?  You don't use the request_mask

Please see Arnd's detailed summary here:

Ah, makes sense, I'd missed that.

Given this, though, it seems like maybe sys_listmount() should enforce
that req->request_mask==0 ?

Thanks,
