   3 Here the status of the work in progress for LTT experimental<br>
   4 <br>
   5 * Done<br>
   6 remove ltt-headers.h<br>
   7 remove ltt-log.h<br>
   8 Put trace->active later in _ltt_trace_start()<br>
   9 ltt_trace_create() remove sleep in spinlock use GFP_ATOMIC kmalloc<br>
  10 Fix the locking of module hooks.<br>
  11 Fix the traps -> disable nested logging for now.<br>
  12 Use per cpu spinlock on trace list.<br>
  13 Finish the control module, libltt and lttctl : netlink interface<br>
  14 <br>
  15 <br>
  16 * TODO<br>
  17 Finish integrating lttctl with lttd.<br>
  18 Add information in the buffer header : buffer size, etc etc...<br>
  19         -> this information is so small that we can repeat it. Makes flight recorder
  20         easier to decode.<br>
  21 Add trace start structure to facility channel.<br>
  22 <br>
  23 <br>
  24 <br>
  25 * TODO (low priority)<br>
  26 Integrate header generation (genevent) in kernel build system.<br>
  27 Multithreaded lttd.<br>
  28 <br>
  29 * Need to be discussed<br>
  30 Drop ltt-module-register and ltt-module-unregister, use exported variables.<br>
  31 RelayFS ioctl interface vs control through LTT netlink interface.<br>
  32 drop ltt_filter_control, use functions pointers instead.<br>
  33 Merge facilities headers into one big header.<br>
  34 Change the name of XML files from XML to something else.<br>
  35 Remove ltt-base.c.<br>
  36 <br>
  37 * Not planned for integration<br>
  38 Remove the callback struct from the trace struct.<br>
  39 <br>
  40 <br>
  41 <br>
  42 * Next experimental release patch division :<br>
