Ming Lei 5b616a05de block: partition: initialize percpuref before sending out KOBJ_ADD ... commit b30a337ca27c4f40439e4bfb290cba5f88d73bb7 upstream. The initialization of partition's percpu_ref should have been done before sending out KOBJ_ADD uevent, which may cause userspace to read partition table. So the uninitialized percpu_ref may be accessed in data path. This patch fixes this issue reported by Naveen.
