Testing branch should be good, though. OK, I'll pick up changes from -testing until directed elsewhere. BTW, here are couple things I've noticed with bcache: - The log messages seem to have an extra newline at the end. - bcache doesn't appear to be establishing proper holders on the devices it uses for the backing and cache devices. - lsblk doesn't show any associations with bcache devices. - the fio utility isn't able to get any stats for the bcache device or the devices bcache uses. - if I 'stop' a bcache device (using sysfs) while it is mounted; once I unmount the filesystem the device that bcache was using as a cache still has an open count of 1 but the bcache device then no longer exists -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
