[PATCH] per-task-delay-accounting: /proc export of aggregated block I/O delays
Shailabh Nagar authored 

Export I/O delays seen by a task through /proc/<tgid>/stats for use in top
etc.

Note that delays for I/O done for swapping in pages (swapin I/O) is clubbed
together with all other I/O here (this is not the case in the netlink
interface where the swapin I/O is kept distinct)
