[I'm not subscribed, hopefully this threads] Um, is this a new application or have you done this before? It's my understanding that very few (or no) CF devices do wear-levelling internally. Using a journal, especially a true data journal, seems like *the* way to wear out your flash as quickly as possible. If you've had success using ext2 in read/write mode on flash/CF in a shipping product, I for one would like to know more details! ken - 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/
