Thanks. I am terribly sorry about this patch series to be honest, I did
not prepare it properly and sent too many generic patches at once but
more importantly some were unsafe (strlcpy expects the input string to
be validly formatted, because it basically does strlen() on it to check
how much hasn't been copied for its return value)
I was pointed out strscpy instead as a safer alternative.

In this case `name` comes from bdevname() which is disk_name() in
block/partition-generic.c which is a snprintf, so we are guaranted
null truncation from there and it should be OK, but I wanted to check
and point it out.

Anyway, thanks!
