b0e0e1f83d [media] media: videobuf2: Prepare to divide videobuf2 
Prepare to divide videobuf2
- Separate vb2 trace events from v4l2 trace event.
- Make wrapper functions that will move to v4l2-side.
- Make vb2_core_* functions that will remain in core-side.
- Add a callback function table for buffer operation which makes vb2-core
  to be able to invoke a v4l2-side functions.
- Rename internal functions as vb2_*.

c139990e84 [media] media: videobuf2: Replace videobuf2-core with videobuf2-v4l2 
Make videobuf2-v4l2 as a wrapper of videobuf2-core for v4l2-use.
And replace videobuf2-core.h with videobuf2-v4l2.h.
This renaming change should be accompanied by the modifications
of all device drivers that include videobuf2-core.h.
It can be done with just running this shell script.

replace()
{
str1=$1
str2=$2
dir=$3
for file in $(find $dir -name *.h -o -name *.c -o -name Makefile)
do
    echo $file
    sed "s/$str1/$str2/g" $file > $file.out
    mv $file.out $file
done
}

replace "videobuf2-core" "videobuf2-v4l2" "include/media/"
replace "videobuf2-core" "videobuf2-v4l2" "drivers/media/"
replace "videobuf2-core" "videobuf2-v4l2" "drivers/usb/gadget/"
replace "videobuf2-core" "videobuf2-v4l2" "drivers/staging/media/"

9deb6ad661 [media] v4l2: move tracepoint generation into separate file 
To compile videobuf2-core as a module, the vb2_* tracepoints must be
exported from the videodev module. Instead of exporting vb2 tracepoint
symbols from v4l2-ioctl.c, move the tracepoint generation into a separate
file. This patch fixes the following build error in the modpost stage,
introduced by 2091f5181c ("[media] videobuf2: add trace events"):

    ERROR: "__tracepoint_vb2_buf_done" undefined!
    ERROR: "__tracepoint_vb2_dqbuf" undefined!
    ERROR: "__tracepoint_vb2_qbuf" undefined!
    ERROR: "__tracepoint_vb2_buf_queue" undefined!
