Subject[PATCH] lightnvm: fix incorrect nr_free_blocks stat
Message-ID<qFyyf-4PE-25@gated-at.bofh.it>
When initing bad block list in gennvm_block_bb, once we move bad block
from free_list to bb_list, we should maintain both stat info
nr_free_blocks and nr_bad_blocks. So this patch fixes to add missing
operation related to nr_free_blocks.
