| From | Andi Kleen <> | Subject | [PATCH] [27/139] PM / Hibernate: Fix PM_POST_* notification with user-space suspend | Date | Tue, 1 Feb 2011 16:43:42 -0800 (PST) |
| |
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.
