Kind of an inadequate changelog ;) Is this a fix or an enhancement or what? > + if (atomic_read(&shca->num_cqs) >= ehca_max_cq) { > + if (atomic_read(&shca->num_qps) >= ehca_max_qp) { These are racy in the sense that multiple simultaneous calls to create_cq/create_qp might end up exceeding the ehca_max_cq limit. Is that an issue? You could close the race by using atomic_add_unless() and testing the return value (and being careful to do atomic_dec() on error paths after you bump num_cqs/num_qps). - R. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
