In the kernel command-line, previously, root=1:2jakshflaksjdhfa would be accepted and interpreted just like root=1:2. This patch adds stricter checking so that additional characters after major:minor are rejected by root=. The goal of this change is to help in unifying DM's interpretation of its block device argument by using existing kernel code (name_to_dev_t). But DM rejects malformed major:minor pairs, it seems reasonable for root= to reject them as well.
