Hi all,
This series here implements an interface to enable cpu access from the kernel context to dma_buf objects. The main design goal of this interface proposal is to enable buffer objects that reside in highmem.
Comments, flames, ideas and questions highly welcome. Althouhg I might be a bit slow in responding - I'm on conferences and vacation the next 2 weeks.
Cheers, Daniel
