(I had meant to say linux-next repo above.)

I'm curious --- are you having to do anything special in terms of
deleting old tags to keep the size of the repo under control? Git
will keep a tag around indefinitely, so if you have huge numbers of
next-YYYYMMDD tags in your repo, the size will grow without bound.
Are you doing anything to automatically garbage collect tags to preven
this from being a problem?

(I am not pulling linux-next every day; only when I need to debug a
bug reported against the -next tree, so I just manually delete the
tags as necessary. So I'm curious what folks who are following
linux-next are doing, and whether they have something specific for
linux-next tags, or whether they have a more general solution.)

Cheers,

- Ted
