Looks good to me. I a
Commit 5cf4537975bb ("dma-mapping: introduce a dma_common_find_pages
helper") changed invalid input check in dma_common_free_remap() from:
if (!area || !area->flags != VM_DMA_COHERENT)
to
if (!area || !area->flags != VM_DMA_COHERENT || !area->pages)
which seem to produce false positives
Hi Andrey,
thanks for the patch. I think it would be much easier to just
use the original open coded check in dma_common_free_remap instead
of adding a new helper. What do you think of the version below?
