They can be swapped out. Actually you were right: there's no sleeping call here after doing the mapping. I've updated this call with kmap_atomic. The other function that uses kmap can't be converted since we continue to map several pages in a loop (depending on the length of the DMA region) and hence can't use kmap_atomic there. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
