2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------ From: Rafael J. Wysocki <[email protected]> commit 9744997a8a2280e67984d4bffd87221d24f3b6b1 upstream. If the process using the hibernate user space interface closes /dev/snapshot after creating a hibernation image without thawing tasks, snapshot_release() should call pm_restore_gfp_mask() to restore the GFP mask used before the creation of the image. Make that happen. Tested-by: Alexandre Felipe Muller de Souza <[email protected]> Signed-off-by: Rafael J.
