No, CONFIG_MTD_UBI_FASTMAP is "no", it is switched off.
I used integck. Here is the command I was using:
$ sudo modprobe nandsim && sudo modprobe ubi mtd=0 && sudo ubimkvol -N test -m /dev/ubi0 && sudo modprobe ubifs && sudo mount -t ubifs /dev/ubi0_0 /mnt/ubifs/ && cd /home/dedekind/git/mtd-utils/tests/fs-tests/integrity && sudo sh -c 'echo 1 > /sys/kernel/debug/ubi/ubi0/tst_emulate_bitflips' && sudo ./integck -n2 /mnt/ubifs/
(sorry, you can easily split it).
