The patch titled devmem: handle class_create() failure has been removed from the -mm tree. Its filename was devmem-handle-class_create-failure.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: devmem: handle class_create() failure From: Anton Blanchard <anton@xxxxxxxxx> I hit this when we had a bug in IDR for a few days. Basically sysfs would fail to create new inodes since it uses an IDR and therefore class_create would fail. While we are unlikely to see this fail we may as well handle it instead of oopsing.
