Subject[PATCH] [27/139] PM / Hibernate: Fix PM_POST_* notification with user-space suspend
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Takashi Iwai <tiwai@suse.de>

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.
