From 80d26af89a7249aa5475467000322163c60cdd72 Mon Sep 17 00:00:00 2001 From: Mandeep Singh Baines Date: Wed, 27 Feb 2013 17:03:20 -0800 Subject: coredump: use a freezable_schedule for the coredump_finish wait Prevents hung_task detector from panicing the machine. This is also needed to prevent this wait from blocking suspend. (It doesnt' currently block suspend but it would once the next patch in this series is applied.)
