2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: John Stoffel commit 14d9fa352592582e457cf75022202766baac1348 upstream. Make Block Layer SG support v4 the default, since recent udev versions depend on this to access serial numbers and other low level info properly. This should be backported to older kernels as well, since most distros have enabled this for a long time.
