[032/152] PM / Hibernate: Fix PM_POST_* notification with user-space suspend

From: Greg KH
Date: Wed Jan 05 2011 - 19:58:03 EST


2.6.36-stable review patch. If anyone has any objections, please let us know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit 1497dd1d29c6a53fcd3c80f7ac8d0e0239e7389e upstream.

The user-space hibernation sends a wrong notification after the image
restoration because of thinko for the file flag check. RDONLY
corresponds to hibernation and WRONLY to restoration, confusingly.
