Re: [PATCH 0/7] [RFC] kernel: add a netlink interface to get information about processes

task_diag is based on netlink sockets and looks like socket-diag, which
is used to get information about sockets.

A request is described by the task_diag_pid structure:

struct task_diag_pid {
       __u64   show_flags;      /* specify which information are required */
       __u64   dump_stratagy;   /* specify a group of processes */

       __u32   pid;
};

Can you explain how the interface relates to the 'taskstats' genetlink
API? Did you consider extending that interface to provide the
information you need instead of basing on the socket-diag?
