UBI: add ioctl compatibility 2009-01-18T12:27:41+00:00 Artem Bityutskiy Artem.Bityutskiy@nokia.com 2009-01-16T16:06:55+00:00 f429b2ea8eadb5a576542a70f7fd6f5c2a7455e1 UBI ioctl's do not work when running 64-bit kernel and 32-bit user-land. Fix this by adding the compat_ioctl method. Also, UBI serializes all ioctls, so more than one ioctl at a time is not a problem. Amd UBI does not seem to depend on anything else, so use unlocked_ioctl instead of ioctl (no BKL needed).
