This patchset proposes to introduce a "staging" module option to dynamically enable features (mostly ioctls) that are merged but may be refined before they are declared "stable". The second patch illustrates the use of this staging option with the SET_TILING ioctl, which can be used to specify the tiling options of a PRIME-imported buffer. The staging parameter will allow us (especially, us at NVIDIA) to experiment more freely with new features and avoid carrying patches across version. To prevent abuse, the number of staging IOCTLs is limited to 8 (range 0x98 to 0xa0) that are to be recycled as staging IOCTLs become stable and are assigned a final number.
