Subject: [PATCH] block: add partition uuid into uevent as "PARTUUID"
5+
6+
Both most common formats have uuid in addition to partition name:
7+
GPT: standard uuid xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
8+
DOS: 4 byte disk signature and 1 byte partition xxxxxxxx-xx
9+
10+
Tools from util-linux use the same notation for them.
