[ltt-dev] ** ERROR **: Kernel/LTTV event size differs for event tree_call_rcu_bh

[Naresh Bhat]

Hi Mathew/Alexandre Montplaisir,

I have executed all the test cases with lttng-kernel patch level*lttng-0.188
*. I have also executed only one test case with following combination
*ttng-0.190,
lttv 0.12.29 and lttc 0.78* but the results are failed.

*Thanks in advance
-Naresh Bhat*
