Can you consider embedding the lock and unlock inside qed_bmap_release_id? There are two places where this is bad idea as driver needs to release two IDs but still one is in error flow and second is when destroying QP so for most cases code may look a bit better. > > return rc; > -- > 1.8.3.1 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-rdma" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
