Jerome Glisse a698cf34ea drm: mm always protect change to unused_nodes with unused_lock spinlock ... unused_nodes modification needs to be protected by unused_lock spinlock. Here is an example of an usage where there is no such protection without this patch. Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list) 2-spin_lock(spinlock protecting mm struct) 3-drm_mm_put_block(this function might modify unused_nodes list but doesn't protect modification with unused_lock) 4-spin_unlock(spinlock protecting mm struct) Process2: 1-drm_mm_pre_get(this function modify unused_nodes list) At this point Process1 & Process2 might both be doing modification to unused_nodes list. This patch add unused_lock protection into drm_mm_put_block to avoid such issue.
