Dv4l2-framework.txt75 and the v4l2_fh struct keeps track of filehandle instances.
923 struct v4l2_fh
926 struct v4l2_fh provides a way to easily keep file handle specific data
927 that is used by the V4L2 framework. New drivers must use struct v4l2_fh
930 The users of v4l2_fh (in the V4L2 framework, not the driver) know
931 whether a driver uses v4l2_fh as its file->private_data pointer by
935 struct v4l2_fh is allocated as a part of the driver's own file handle
939 In many cases the struct v4l2_fh will be embedded in a larger structure.
