They are, but the inode fileserver isn't implemented in Linux because
Linux doesn't provide the necessary hooks.  You have a choice on Solaris,
but not Linux.  On linux your only choice is the namei fileserver.


PS: The inode fs on Solaris has been measured to be about 10% faster
than the namei fileserver, so you do gain some speed, but not
necessarily enough to offset the pain and suffering of using the wrong
fsck on your file system and losing all your data.  :)
