CVE-2026-72494

RDMA/irdma: Replace waitqueue and flag with completion

In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Replace waitqueue and flag with completion

The driver previously used a waitqueue along with an explicit

requestdone flag, but without proper barriers around requestdone.

An earlier patch by Gui-Dong Han hanguidong02@gmail.com attempted

to fix this by adding the missing memory barriers. Rather than

adding the barriers, this patch replaces the waitqueue+flag with

a completion, which is designed for this exact purpose.
