The mentioned function use GFP_ATOMIC to to alloc a crypto instance, and then calls alloc_ordered_workqueue() which allocates memory with GFP_KERNEL. tipc_aead_init() function even uses GFP_KERNEL and GFP_ATOMIC interchangeably. No doc comment specifies what context a function is designed to work in, but the flags should at least be consistent within a function. Cc: Jon Maloy Cc: Ying Xue Cc: "David S.
