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 4.4, the vivid driver (since that
emulates almost all V4L2 ioctls that need to pass through v4l2-compat-ioctl32.c)
and a 32-bit v4l2-compliance utility since that exercises almost all ioctls
as well. Combined this gives good test coverage.
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
