a/b/c/d/ where `a/b/c/` exists results in additional syscalls such as an Lstat() call to verify if the `a/b/c/` exists and its a directory. We do not need to do this on MinIO since the parent prefixes if exist, we can simply return success without spending additional syscalls. Also this implementation attempts to simply use Access() calls to avoid os.Stat() calls since the latter does memory allocation for things we do not need to use. Access() is simpler since we have a predictable structure on the backend and we know exactly how our path structures are.
