Applied, thanks! I had to add a C++ acceptable alternative but it was
not difficult:
#ifndef __cplusplus
#define PADDED_MEMBERS_CACHELINE_MARKER(UNIT, CACHELINE, MEMBERS) \
union { \
OVS_CACHE_LINE_MARKER CACHELINE; \
struct { MEMBERS }; \
uint8_t PAD_ID[ROUND_UP(sizeof(struct { MEMBERS }), UNIT)]; \
}
#else
#define PADDED_MEMBERS_CACHELINE_MARKER(UNIT, CACHELINE, MEMBERS) \
union { \
OVS_CACHE_LINE_MARKER CACHELINE; \
struct { MEMBERS }; \
struct { MEMBERS } named_member__; \
uint8_t PAD_ID[ROUND_UP(sizeof named_member__, UNIT)]; \
}
#endif
