I need to check for this in the patches (and you may be doing this already), but in the kernel failed checksums should result in an ext4_error() call which will set the file system as corrupt and needing to be checked. And in e2fsck it should force a full check of the file system. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
