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
request_done flag, but without proper barriers around request_done.
An earlier patch by Gui-Dong Han <[email protected]> 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.
