Between 2.6.20 and 2.6.21-rc1 there are only: $ git rev-list --no-merges v2.6.20..v2.6.21-rc1 |wc -l 3118 patches, requiring 14 boots. In general ceil(log(n)/log(2))+2 boots. Of course, this is a little optimistic because it assumes no additional breakage occurring at the various bisection points. In any event, assuming (pessimistically) 10 minutes per build, this is 280 minutes or 4 hours and 40 minutes of build time. I estimate the process should complete well before Friday of this week, never mind June. -- wli
