Hi Alin, actually if your config has no CONFIG_MEM_SOFT_DIRTY=y then the fix won't help, it might be some different issue (Dave has been testing the kernel with soft-dirty option set). But of course I don't mind if you test the kernel with soft dirty option turned on. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
