#     tmpfs: fix uninitialized return value in shmem_link
#     
#     When we made the shmem_reserve_inode call in shmem_link conditional, we
#     forgot to update the declaration for ret so that it always has a known
#     value.  Dan Carpenter pointed out this deficiency in the original patch.
#     
#     Fixes: 1062af920c07 ("tmpfs: fix link accounting when a tmpfile is linked in")
