H A D | opal-irqchip.c | 331e2cad Tue May 09 22:31:15 CDT 2023 Rohan McLure <rmclure@linux.ibm.com> powerpc: powernv: Annotate data races in opal events
The kopald thread handles opal events as they appear, but by polling a static bit-vector in last_outstanding_events. Annotate these data races accordingly. We are not at risk of missing events, but use of READ_ONCE, WRITE_ONCE will assist readers in seeing that kopald only consumes the events it is aware of when it is scheduled. Also removes extraneous KCSAN warnings.
