stable inclusion from stable-v5.10.137 commit 9260a154b3b5e387dbceec7c0ac441470646bc6f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 54eb7a55be6779c4d0c25eaf5056498a28595049 ]
'erased_blocks_bitmap' is never freed. As it is allocated at the same time as 'used_blocks_bitmap', it is likely that it should be freed also at the same time.
Add the corresponding bitmap_free() in msb_data_clear().
