The fundamental difference that makes it reliable is that: 1) only the I/O we're throttling against will be considered for the wakeup event, which means only clearing PG_writeback will be considered eligible for wakeup Currently _all_ unrelated write I/O was considered eligible for wakeup events and that could cause spurious oom kills. 2) we won't need unreliable anti-deadlock timeouts anymore - 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/ | ||||||||||||
