[lttng-dev] trace_block_rq_complete duplicate define

[loody]

hi all:
My environment is like below:
1. kernel 3.8.13
2. lttng modules is 2.4.0 ( i also try lttng-modules-2.3.5 but result
is the same)
I will get "trace_block_rq_complete duplicate define" like below:
is there kernel or lttng modules patch I need to fix this compile error?

Thanks for your help in advance,
