Anything, the more formal or more widespread the better. I just don't think it's used much this way today... We can start with xfstests etc but I'd be more concerned about unexpected behavioral or performance changes. > I admit I like having ext2 around for comparisons in bug situations. > It really helps to isolate the problem area.

In distro-land, I often have bugfixes that need to hit 2 or 3 of the filesystems as well. -Eric > mrubin > -- > To unsubscribe from this list: send the line "unsubscribe linux-ext4" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
