In fact that assumption is fairly trivial to remove, if you can put an upper bound on the growth. Adding encryption of data to JFFS2 would actually be fairly trivial; encryption of metadata would be harder. You could do it without touching or grokking the core of JFFS2 at all -- just poke at fs/jffs2/compr.c and note that you're expected to eat as much of the input as will fit into the output buffer, returning success even if it didn't all fit. -- dwmw2 - 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/ | ||||||||||||
