What do you mean with global? Global is one thing, but taking highmem into account for calculating the limit is another thing. The nr_free_buffer_pages exists exactly to avoid taking highmem into account for the dirty memory limits. 2.6 must also ignore highmem in the dirty memory limits like 2.4 does. I'd be surprised if somebody broke this in 2.6. As far as I can tell, while writing to a blkdev it cannot make any difference if you've 4G or 1G of ram because of that (I mean on x86 of course). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
