Cover letter [patch 0/9] videobuf fixes 2.6.25
Hello-
The following set fixes problems I discovered while tracking down bugs in both vivi and videobuf. Hopefully most of these can make it into 2.6.25 since they all seem pretty critical.
Please take a good look at the set and test if possible. Particularly:
[RFC] videobuf: Avoid deadlock with QBUF
Also, is anyone using videobuf-vmalloc besides vivi? The current videobuf API feels over extended trying to take on the task of a second backend type.
Thanks,
Brandon
