Subject[34-longterm 170/209] PM / Hibernate: Fix PM_POST_* notification with user-space suspend
Date
From: Takashi Iwai <tiwai@suse.de>

=====================================================================
| This is a commit scheduled for the next v2.6.34 longterm release. |
| If you see a problem with using this for longterm, please comment.|
=====================================================================

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.
