I think I could find the root cause.
In fs/fuse/dir.c:fuse_link(), we see the comment.
/* Contrary to "normal" filesystems it can happen that link
makes two "logical" inodes point to the same "physical"
inode. We invalidate the attributes of the old one, so it
will reflect changes in the backing inode (link count,
etc.)
*/
In your case, aufs finds two different inodes (which should be one), and
stops working since this is unusual situation. If you set
CONFIG_AUFS_DEBUG, you will see the message from aufs.
Now what should the solution be?
- make fuse an ordinary filesystem whose link(2) doesn't make another
inode.
- make aufs to support such filesystem whose link(2) creates another
inode.
- etc.
I don't know the answer.
I am still thinking...
