Hello, I am trying to use LTTNG on centos (2.6.32). I have applied the given patch and rebuilt a kernel. Still I am unable to build the lltng-modules.

Kernel was built by disabling "CONFIG_MODULE_SIG". Could you please kindly guide me on this issue. Appreciate your help very much. Please do let me know, if I need to provide any more info on this.
