When using 'ls -l' to display a large directory, if noac option is used, in function nfs_getattr() nfs_need_revalidate_inode() will always be true for NFSv3 and the nfs_entry cache of the directory will be flushed. The flush will lead to a fully reread of the directory entries from server. To prevent the unnecessary RPCs, we need to check whether or not the noac option is used, and always report the invocation of nfs_getattr() as cache hit instead cache miss when it's on.
