------------------------------------------------------ From: Sebastian Andrzej Siewior bigeasy@linutronix.de Subject: dma: kmsan: export kmsan_handle_dma() for modules Date: Tue, 18 Feb 2025 10:14:11 +0100

kmsan_handle_dma() is used by virtio_ring() which can be built as a module. kmsan_handle_dma() needs to be exported otherwise building the virtio_ring fails.

Export kmsan_handle_dma for modules.
