Hou Tao 75a442581d bpf: Add missed allocation hint for bpf_mem_cache_alloc_flags() ... bpf_mem_cache_alloc_flags() may call __alloc() directly when there is no free object in free list, but it doesn't initialize the allocation hint for the returned pointer. It may lead to bad memory dereference when freeing the pointer, so fix it by initializing the allocation hint. Fixes: 822fb26bdb ("bpf: Add a hint to allocated objects.")
