+ int index = ((char *)cache_info_addr - (char

+ cache->info_index = (index + 1) % PCACHE_META_INDEX_MAX;
Don't advance info_index at init stage, cache->info_index means the
current index, not the next index.
It will be advanced in cache_info_write() after write cache_info into
next slot.
My bad, ->info_index means next slot, so advance it is correct.
In addition, cache->info_index initialization should be after the
data_crc checking.
Thanx
