Eric Sandeen 6f4f371426 ext3: return 32/64-bit dir name hash according to usage type ... commit d7dab39b6e upstream. This is based on commit d1f5273e9a ext4: return 32/64-bit dir name hash according to usage type by Fan Yong <yong.fan@whamcloud.com> Traditionally ext2/3/4 has returned a 32-bit hash value from llseek() to appease NFSv2, which can only handle a 32-bit cookie for seekdir() and telldir(). However, this causes problems if there are 32-bit hash collisions, since the NFSv2 server can get stuck resending the same entries from the directory repeatedly. Allow ext3 to return a full 64-bit hash (both major and minor) for telldir to decrease the chance of hash collisions. This patch does implement a new ext3_dir_llseek op, because with 64-bit hashes, nfs will attempt to seek to a hash "offset" which is much larger than ext3's s_maxbytes. So for dx dirs, we call generic_file_llseek_size() with the appropriate max hash value as the maximum seekable size. Otherwise we just pass through to generic_file_llseek().
