2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Henrique de Moraes Holschuh This issue was fixed indirectly in mainline by commit 0175d562a29ad052c510782c7e76bc63d5155b9b. acpi_namespace_node's name.ascii field is four chars, and not NULL- terminated except by pure luck. So, it cannot be used by sscanf() without a length restriction. This is the minimal fix for both stable 2.6.27 and 2.6.28.
