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

[Naresh Bhat]

Hi All,

With 2.6.32.4-lttng-0.188 kernel and Linux Trace Toolkit Trace Daemon
0.78-04122009 combination on my x86 32 bit target board lttng test throw "**
ERROR **: Kernel/LTTV event size differs for event tree_call_rcu_bh" error.


Is this a know issue ? If not, can you please, give me some guidance to
overcome from this problem ?
