As we have the fuzzed images in progs, I started prototyping a way to export just the testsuite from the git repository, to a tarball. The test would then iterate over the stored images and attempt to mount them. So any images you'd like mount-tested, also submit to btrfs-progs. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
