This is the first of a series of oom related fix I'm going to do and test within the next weeks to attempt to cure various oom regressions in 2.6 (deadlocks turned into crazy early oom kills and the like). - 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/
