If anyone has any objections, please let me know. ------------------ From: Zeev Tarantov [Patch not needed upstream as this is a backport build bugfix - gregkh gcc correctly complains: util/hist.c: In function ‘__hists__add_entry’: util/hist.c:240:27: error: invalid type argument of ‘->’ (have ‘struct hist_entry’) util/hist.c:241:23: error: invalid type argument of ‘->’ (have ‘struct hist_entry’) for this new code: + if (he->ms.map != entry->ms.map) { + he->ms.map = entry->ms.map; + if (he->ms.map) + he->ms.map->referenced = true; + } because "entry" is a "struct hist_entry", not a pointer to a struct. In mainline, "entry" is a pointer to struct passed as argument to the function. So this is broken during backporting. But obviously not compile tested.
