At least, if the implementation was competently coded.... (ext2/3/4 has feature bitmasks that make it very clear what features are required so that an implementation can mount the file system read/write or read/only). - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
