Regular kmem_getpages is called with GFP_THISNODE set. There was some breakage in 2.6.22 and before with GFP_THISNODE returning pages from the wrong node if a node had no memory. So it may have worked accidentally and in an unsafe manner because the pages would have been associated with the wrong node which could trigger bug ons and locking troubles. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
