- Thread-topic: [PATCH] [TRIVIAL] Xenperf perfc_defn
perfc_defn.h is used to initialise an array of performance counter structures. However, it is included twice to initialise two arrays (perfcounter in perfc.h and perfc_info in perfc.c). The usual header file guard (#ifndef..., #define..., #endif) prevents these two arrays being initialised with the contents of perfc_defn.h in the same file. This patch fixes this and allows Xenperf to work properly.
