Frequently Asked Questions

1

Which allocation path is affected by this defect?

The issue affects dma_direct_alloc_pages(), which uses dma_direct_alloc_from_pool() and expects that helper to return a struct page pointer. The regressed helper instead returned a CPU address.

2

What change resolves the issue?

The fix restores dma_direct_alloc_from_pool() returning a struct page pointer and passes the CPU address to dma_direct_alloc() through an output parameter.
