So I guess it's doing some direct IO that appends to a file and then a stat to confirm that we get the new i_size? If this isn't working when run on an NFS filesystem, then I think either the client isn't asking the server for the new i_size, or maybe it's asking but getting a bad response. The bad response might have the old i_size. Or I wonder if the client would be confused if the server failed to update the change attribute (i_version) for some reason? Does this test fail when we export other filesystems? Is the failure new, or has it always failed? --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
