I'd lean towards saying drop, and rely on userspace to do something useful. Personal experience is that if two oopses are unrelated then there's enough time for userspace to do something and remove the existing record, and if they're related it's the first one that tells you where the problem actually is. One thing that's worth noting - UEFI systems will typically only recover deleted space on reset. create->delete->create->delete will reduce available space until the platform is rebooted, at which point the deleted portion will become available again. -- Matthew Garrett | mj...@srcf.ucam.org -- 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/
