[PATCH v2 0/2] Fix high cpu usage of ubi_bgt thread

[Zhihao Cheng]

v1->v2:
  Update fm pool filling strategy, consider reserve enough free count
  for fastmap non anchor pebs while filling fm_wl_pool.
  Remove 'fm_next_anchor' and check 'fm_anchor' during wear leveling.
  Check wl_pool for free peb before wear leveling.
