Ah, whoops. "Block cache" - it uses one block device to cache another, it's intended for SSDs. It's summarized decently in the documentation patch, which if I'd thought harder would've been the first email... http://thread.gmane.org/gmane.linux.kernel/979977 Second patch also has relevant commentary: http://thread.gmane.org/gmane.linux.kernel/979978 http://thread.gmane.org/gmane.linux.kernel/979979 Currently all the necessary functionality for read only is close to done, I'm now doing stress testing. I'm hoping to have it Stable For Me and read/write done in a week or two, at which point it should be ready for people to start playing with. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
