Subject: [PATCH] lightnvm: fix incorrect nr_free_blocks stat
Date: Mon, 14 Dec 2015 18:23:29 +0800 [thread overview]
Message-ID: <006401d13659$8f89ff70$ae9dfe50$@samsung.com> (raw)
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.
