Thanks!
I had to adjust the patch a bit for the debugfs cleanups form Greg
that I applied before, can you check the result here:
http://git.infradead.org/users/hch/dma-mapping.git/commitdiff/0a3b192c26da198fce38e1ee242a34f558670246
While debugging a DMA mapping leak, I needed to access
debug_dma_dump_mappings() but easily from user space.
This patch adds a /sys/kernel/debug/dma-api/dump file which contain all
current DMA mapping.
