[PATCH] ceph: use 2 instead of 1 as fallback for 32-bit inode number

[PATCH] ceph: use 2 instead of 1 as fallback for 32-bit inode number

[Alex Elder]

The root directory of the Ceph mount has inode number 1, so falling back
to 1 always creates a collision. 2 is unused on my test systems and seems
less likely to collide.
