From d75d6f294e0e011e53913803db70f8096f5fd630 Mon Sep 17 00:00:00 2001 From: Chris Dunlop Date: Thu, 4 Oct 2012 16:19:17 +1000 Subject: [PATCH] Switch KM_SLEEP to KM_PUSHPAGE This warning indicates the incorrect use of KM_SLEEP in a call path which must use KM_PUSHPAGE to avoid deadlocking in direct reclaim.
