What an useful way to describe kernel version.

Could we get reasonable subject line? 4.15-rc7: prefix would be nice
if it is on mainline, net-next: subject if it happens only on next

We don't want dumb bots to send automated emails to 1000s of
people. If it is important enough to be sent to 1000s of people, it is

interface to your robot.

#syz test: git://gcc.gnu.org/git/gcc.git master
