These are inode collisions due to two 96-bit FID's hashing to the same
32-bit inode number in the kernel. They are very annoying because it is
impossible to keep two of these files open at the same time.

Luckily, these occur mostly between files and directories, such as in
this case, i.e. odd middle numbers in the FIDs are directories while the
even numbers represent files.
