I can read every file (no read error), in dmesg appear new messages about wrong checksum and this files are putted into kernel cache. I can read particular file again and again, no new message about checksum appears. Then I'm doing echo 3 > ..drop_caches, after this I reread particular file, I'm getting message about wrong checksum. Shouldn't be access to such file disallowed? -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
