From b781a602ac745ee3d5d745276f1e1905a2c101f9 Mon Sep 17 00:00:00 2001 From: Andrew Vagin Date: Mon, 28 Nov 2011 12:03:35 +0300 Subject: events, sched: Add tracepoint for accounting blocked time This tracepoint shows how long a task is sleeping in uninterruptible state. E.g. it may show how long and where a mutex is waited for.
