Subject[PATCH] block: add partition uuid into uevent as "PARTUUID"
From
Date
Both most common formats have uuid in addition to partition name:
GPT: standard uuid xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
DOS: 4 byte disk signature and 1 byte partition xxxxxxxx-xx

Tools from util-linux use the same notation for them.
