Hi Guys, Recently I am trying cache tier and if I try to stat a non-existent object in both cache tier pool and base pool, I find cache tier will not just return -ENOENT, but also create an empty object with setting its flag as FLAG_WHITEOUT in cache tier pool. Although it indicates this object is not existed logically, why cache tier will try to create it rather than only returning -ENOENT? Thanks.
