I think you are correct in this. act_size = roundup_64(attr->length, MLX5_SW_ICM_BLOCK_SIZE(dm_db->dev)); Where we have: #define MLX5_SW_ICM_BLOCK_SIZE(dev) (1 << MLX5_LOG_SW_ICM_BLOCK_SIZE(dev)) Which pretty much guarantees that it is a power of two. Thus, the real fix here is simply to s/roundup/round_up/ as you suggest. > > On a slight tangent.. Maybe we should have somet...
