That's wrong. In case you would not yet have noticed my latest email in
this thread, please take a look at
https://lore.kernel.org/linux-rdma/e8b76fae-780a-470e-8ec4-c6b650793d10@xxxxxxxxxxxxx/T/#m0fd8ea8a4cbc27b37b042ae4f8e9b024f1871a73.
I think the report in that email is a 100% proof that there is a
use-after-free issue in the rdma_rxe driver. Use-after-free issues have
security implications and also can cause data corruption. I propose to
revert the commit that introduced the rdma_rxe use-after-free unless
someone comes up with a fix for the rdma_rxe driver.
