Note, the CONFIG_MTD_UBI_DEBUG_DISABLE_BGT is debugging option, which
was introduce to test UBI correctness, because theoretically it should
work even if the thread dies or does not exist. However, UBI becomes
less efficient without the thread, so I'd recommend to use it only for
developing/test purposes.

Right, I meant ubifs-v2.6.25.git.
