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

RDMA/irdma: Fix data race on CQP request done

KCSAN detects a data race on cqprequest->requestdone memory location which is accessed locklessly in irdmahandlecqpop while being updated in irdmacqpcehandler.

Annotate lockless intent with READONCE/WRITEONCE to avoid any compiler optimizations like load fusing and/or KCSAN warning.
