| Subject | [PATCH v5 1/7] genirq: export irq_get_percpu_devid_partition to modules |
| Message-ID | <uuHFM-1y2-19@gated-at.bofh.it> |
Any modular driver using cluster-affine PPIs needs to be able to call
irq_get_percpu_devid_partition so that it can enable the IRQ on the
correct subset of CPUs.
This patch exports the symbol so that it can be called from within a
module.
