That's a very bad idea. glibc configured for 2.6.18 and higher kernels assumes PI futexes are present.

smaller kernel with no real time futexes
Adrian, You said earlier you're looking at smaller allnoconfig kernels. One thing I noticed recently that realtime pi futexes are always enabled and that pulls in a lot of other code (like the plists) Userland needs to handle them not being available anyways for older kernels. Might be worth looking into turning that into a CONFIG. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
