This is a problem when JFFS2 cleanmarkers are added to the OOB, since it will

Dear All,
During the Exynos DRM GEM rework and fixing the issues in the.
drm_prime_sg_to_page_addr_arrays() function [1] I've noticed that most
drivers in DRM framework incorrectly use nents and orig_nents entries of
the struct sg_table.
In case of the most DMA-mapping implementations exchanging

One question here is whether the might_sleep should be unconditional,
or only for real timeouts. I'm not sure, so went with the more
defensive option. But in the interest of locking down the

Although DPMS in it's traditional sense is no longer a thing, would it
make sense to keep this around for documentation purposes?

Use common helper for checking the contiguity of the imported dma-buf and
do this check before allocating resources, so the error path is simpler.
