[PATCH OLK-6.6 0/3] Fix shmem_rename2 directory offset calculation

Pull shmem_rename2() offset fixes from Chuck Lever:

The existing code in shmem_rename2() allocates a fresh directory offset value when renaming over an existing destination entry. User space does not expect this behavior. In particular, applications that rename while walking a directory can loop indefinitely because they never reach the end of the directory.
