hmm, with 4 million pages on the inactive list that's 1000 pages. It might be OK.
Bear in mind that under usual circumstances the direct-reclaim path will refuse to block on request queue exhaustion so we might end up just scanning past some dirty pages without starting I/O against them at all. End result: some jumbling up of the LRU order. I suspect that's a second-order problem though. But hey, if we have a testcase, we can fix it! - 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/
