General informations

The Linux kernel configuration item CONFIG_BRANCH_TRACER:

Help text

This traces the events of likely and unlikely condition calls in the kernel. The difference between this and the "Trace likely/unlikely profiler" is that this is not a histogram of the callers, but actually places the calling events into a running trace buffer to see when and where the events happened, as well as their results.

Say N if unsure.
