Dawei Li 606091b2f6 dma-buf: fix racing conflict of dma_heap_add() ... [ Upstream commit 432e25902b ] Racing conflict could be: task A task B list_for_each_entry strcmp(h->name)) list_for_each_entry strcmp(h->name) kzalloc kzalloc ...... ..... device_create device_create list_add list_add The root cause is that task B has no idea about the fact someone else(A) has inserted heap with same name when it calls list_add, so a potential collision occurs.
