------------------------------------------ For what it's worth, I tested this patch on my 3.4 kernel, and it works as advertised. Here's my setup. - 2 GB RAM - a 3 GB zram disk for swapping - start one "hog" process per second (each hog process mallocs and touches 200 MB of memory). - watch /proc/meminfo 1. I verified that the problem still exists on my current 3.4 kernel. With laptop_mode = 2, hog processes are oom-killed when about 1.8-1.9 (out of 3) GB of swap space are still left 2. I double-checked that the problem does not exist with laptop_mode = 0: hog processes are oom-killed when swap space is exhausted (with good approximation). 3. I added the two-line patch, put back laptop_mode = 2, and verified that hog processes are oom-killed when swap space is exhausted, same as case 2. Let me know if I can run any more tests for you, and thanks for all the support so far! -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
