 * TODO<br>
-Fix the locking of module hooks.<br>
-Per cpu read lock on trace structure.<br>
+Add type information per facility : it will help having a standard way
+to understand information coming from both kernel space and user space, and deal
+easily with 64 bits kernel with 64 and 32 bits processes (and with size_t know
+at compile time which can differ inside the same process from one library to
+another).<br>
+fix structures alignment, array and sequences too. -> trace dynamic.<br>
+add per facility alignment (inside structures).<br>
+add control of alignment.<br>
+add user space tracing.<br>

 * TODO (low priority)<br>
 Integrate header generation (genevent) in kernel build system.<br>
+Multithreaded lttd.<br>
+Find a different way to printk from instrumentation : forbidden from schedule
+and wakeup (causes a deadlock).<br>

 * Need to be discussed<br>
 Drop ltt-module-register and ltt-module-unregister, use exported variables.<br>
