commit: 72278f474221abd5c09af5d3a4dff39f9d10948f [11/36] RDMA/ocrdma: Move PD
resource management to driver.
New smatch warnings:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:683 ocrdma_alloc_pd() error: double
free of 'pd'
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:686 ocrdma_alloc_pd() error:
passing non negative 255 to ERR_PTR
This bug is that _ocrdma_pd_mgr_put_bitmap() truncates its
error values to u8. I will push a Smatch check to warn about
these sorts of signedness bugs. Also that function would be
readable if it just returned directly instead of setting the
temporary "status" variable. There are some other similar
typing bugs in this file.
Old smatch warnings:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:1766 ocrdma_destroy_qp() error: we
previously assumed 'qp->rq_cq' could be null (see line 1760)
