My tool DCNS reports three unnecessary usages of GFP_ATOMIC in crypto/ablkcipher.c: crypto/ablkcipher.c, 162: kmalloc(GFP_ATOMIC) in ablkcipher_next_slow crypto/ablkcipher.c, 199: kmalloc(GFP_ATOMIC) in ablkcipher_copy_iv crypto/ablkcipher.c, 315: kmalloc(GFP_ATOMIC) in setkey_unaligned
I meant to manually check the code, but I find that there are many functions calling ablkcipher_next_slow(), ablkcipher_copy_iv() and setkey_unaligned(), so I am not sure whether the above three reports are true.
Could someone help me to validate these reports? Thanks a lot in advance :)
Best wishes, Jia-Ju Bai
