The only way to find these things in a reasonable period of time is to go in and find them. For example, intensive fsx-linux testing with concurrent heavy memory pressure on various filesystems with various block sizes. And of course concurrent signalling. If you're talking about O_DIRECT then iirc I hacked support for that into fsx-linux. I think. Anyway, what _are_ the scenarios in which we think data can be lost? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
