Subject: Mark accesses to global vars in addrcache as 'global'
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=66740581fdf3d830c85a94f81b709e556cd43604;p=users%2Fdhowells%2Fkafs-utils.git

Mark accesses to global vars in addrcache as 'global'

Mark accesses to global vars in the addrcache module as 'global' to make sure
Python doesn't do local access instead.
