Message-ID: <20080711132146.31912.76254.stgit@warthog.procyon.org.uk> Date: Fri, 11 Jul 2008 14:21:46 +0100 From: David Howells <dhowells@...hat.com> To: rjw@...k.pl, akpm@...ux-foundation.org Cc: dhowells@...hat.com, pavel@....cz, linux-kernel@...r.kernel.org Subject: [PATCH] Fix try_to_freeze_tasks()'s use of do_div() Fix try_to_freeze_tasks()'s use of do_div() on an s64 by making elapsed_csecs64 a u64 instead and dividing that. Possibly this should be guarded lest the interval calculation turn up negative, but the possible negativity of the result of the division is cast away anyway. This was introduced by patch 438e2ce68dfd4af4cfcec2f873564fb921db4bb5.
