When a line is selected for recycling by the garbage collector (GC), the line state changes and the invalid bitmap is frozen, preventing invalidations from happening. Throughout the GC, the L2P map is checked to verify that not data being recycled has been updated. The last check is done before the new map is being stored on the L2P table. Though this algorithm works, it requires a number of corner cases to be checked each time the L2P table is being updated. This complicates readability and is error prone in case that the recycling algorithm is modified. Instead, this patch makes the invalid bitmap accessible even when the line is being recycled. When recycled data is being remapped, it is enough to check the invalid bitmap for the line before updating the L2P table.
