After UAPI header file split [1] all user-kernel interfaces were placed under include/uapi/. This patch moves IIO user specific API from: * include/linux/iio/events.h => include/uapi/linux/iio/events.h * include/linux/iio/types.h => include/uapi/linux/iio/types.h Now there is no need for nasty tricks to compile userspace programs (e.g iio_event_monitor). Just installing the kernel headers with make headers_install command does the job. [1] http://lwn.net/Articles/507794/ Signed-off-by: Daniel Baluta <daniel.baluta@xxxxxxxxx> --- I am not sure if this is the right thing to do. I am still trying to understand the inners workings of make headers_install. include/linux/iio/events.h | 30 +----------- include/linux/iio/types.h | 94 +---------------------------------- include/uapi/linux/Kbuild | 1 + include/uapi/linux/iio/Kbuild | 3 ++ include/uapi/linux/iio/events.h | 43 ++++++++++++++++ include/uapi/linux/iio/types.h | 106 ++++++++++++++++++++++++++++++++++++++++ 6 files changed, 155 insertions(+), 122 deletions(-) create mode 100644 include/uapi/linux/iio/Kbuild create mode 100644 include/uapi/linux/iio/events.h create mode 100644 include/uapi/linux/iio/types.h diff --git a/include/linux/iio/events.h b/include/linux/iio/events.h index 03fa332..8ad87d1 100644 --- a/include/linux/iio/events.h +++ b/include/linux/iio/events.h @@ -9,22 +9,8 @@ #ifndef _IIO_EVENTS_H_ #define _IIO_EVENTS_H_ -#include <linux/ioctl.h> -#include <linux/types.h> #include <linux/iio/types.h> - -/** - * struct iio_event_data - The actual event being pushed to userspace - * @id: event identifier - * @timestamp: best estimate of time of event occurrence (often from - * the interrupt handler) - */ -struct iio_event_data { - __u64 id;
