your file probably doesn't have holes.  busybox just thinks it does.
look in util-linux/swaponoff.c and find the "swap file has holes"
error message.  add some printfs near there to check the values
being used in the test:
               if (st.st_blocks * (off_t)512 < st.st_size)

check that they all look right.
