Description
In the Linux kernel, the following vulnerability has been resolved:
dlm: fix dlm_recover_members refcount on error
If dlm_recover_members() fails we don't drop the references of the
previous created root_list that holds and keep all rsbs alive during the
recovery. It might be not an unlikely event because ping_members() could
run into an -EINTR if another recovery progress was triggered again.
