If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9c9414b0eb9f3c10213113f10e1a0b35bb39972f Author: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Sat Jun 25 14:55:56 2022 +0200 memstick/ms_block: Fix a memory leak [ 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().
