We can't have that. Sector/block/etc. checksums - yes. A checksum, signature, hash etc. of the whole file would require actually reading the whole file. It can be done by tripwire or backup, and even by fsck, but not by the filesystem in normal operation. -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
