From: Hugh Dickins <hugh@veritas.com>
LTP on tmpfs hits kernel BUG at mm/shmem.c:680! shmem_delete_inode needs
to truncate_inode_pages for itself now. It's not immediately obvious since
many cases get covered by shmem_truncate's followup truncate_inode_pages:
maybe with thought we can just call it once, but right now fix the BUG.
