Stefan's patch is just in pu at this point, right? I do not think there
is any rushing/release concern. It is too late for either to be in
v2.4.0, so the only decision is whether to aim for "master" or "maint".
To me, they both seem to be in the same ballpark as far as risking a
regression.
The series builds on c1f0ca9 that is on 2.4.0-rc2, so we would need
to wiggle things around to apply to older codebase if we want to fix
the "too many open file descriptor" issue on older maintenance
releases for "update-ref --stdin".
I personally feel that it is OK to ship v2.4.0 without the fix,
leaving "push --atomic" broken, and fix it in v2.4.1, but I kinda
prefer that the final fix to be applicable for older maintenance
releases, at least to 2.3.x track, if not 2.2.x track.
