Hi Russell,

2017-03-31 Russell King rmk+kernel@arm.linux.org.uk:

Add debugfs output to report shared and exclusive fences on a dma_buf object. This produces output such as:

Dma-buf Objects: size flags mode count exp_name 08294400 00000000 00000005 00000005 drm Exclusive fence: etnaviv 134000.gpu signalled Attached Devices: gpu-subsystem Total 1 devices attached

Total 1 objects, 8294400 bytes

Our maintainer tools warned about this line, so I made it "unsigned int"
