Good point. That sounds like for the !fc->posix_acl case we just need a careful use of "forget_all_cached_acls(inode)". I will take a quick look at that, and see if that is easy/sufficient to cover the legacy fuse case. Otherwise I will go with what I already have here. That feels like a better path. And internally I would call what is today fc->posix_acl fc->cached_posix_acl. To better convey the intent. Fingers crossed. Eric
