From: Hans Verkuil <hans.verkuil@xxxxxxxxx>
This patch series fixes a number of bugs and culminates in the removal
of the set_fs(KERNEL_DS) call in v4l2-compat-ioctl32.c.
This was tested with a VM running 3.2, the vivi driver (a poor substitute for
the much improved vivid driver that's available in later kernels, but it's the
best I had) since that emulates the more common V4L2 ioctls that need to pass
through v4l2-compat-ioctl32.c) and the 32-bit v4l2-compliance + 32-bit v4l2-ctl
utilities that together exercised the most common ioctls.
Most of the v4l2-compat-ioctl32.c do cleanups and fix subtle issues that
v4l2-compliance complained about. The purpose is to 1) make it easy to
verify that the final patch didn't introduce errors by first eliminating
errors caused by other known bugs, and 2) keep the final patch at least
somewhat readable.
Regards,
Hans
