From ba367276d84e126dc3a13677c286539d0019e3b8 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Mon, 17 Sep 2012 11:22:23 -0700 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. See commit b8d06fca089fae4680c3a552fc55c512bfb02202 for additional details.
