Weird, perhaps you hit an unlucky revision. I only use the git branch for development, and it's continually rebased to collect and split patches and fixes. So I don't generally recommend to use that, just the posted patches. I build -j8 or larger kernels with the writeback patches all the time, and haven't seen any issues. That's on a core 2 quad. Just for kicks, can you send me your .config? I'll post a new revision tomorrow, if you could try that I'd appreciate it! > Maybe it does need the congestion handling after all? No it does not, by the very nature of the bdi threads being blocking, congestion is not relevant. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
