You may say that doing multiple parallel lseek() calls is undefined behaviour, so it's ok to end up with file position that none of the individual lseek() calls asked for. But if it's undefined behaviour, no programs should be doing parallel lseek() calls on the same open file, so why optimise it at all? -- Jamie -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
