I forgot to mention that I've take a stricter view since doing this series so it needs an update even in the tree above. This mostly affects err.h, errno.h, stddef.h and types.h I'll update those in that tree sometime this week. > > Thanks, > > Jonathan > > > > > This series is based loosely on the suggests the > > include-what-you-use tool provides but with a lot of discretion applied. > > Note that tool will tell you: > > 1) What includes provide elements directly used in a given .c file. > > 2) What includes are providing nothing that is directly used in the .c file. > > 3) It will not follow 'include chains', then concept being that anything > > used should be defined in a header directly included. > > It can't always distinguish between different paths to the header and > > knows nothing about intended include structures in the kernel. > > (for example including eventpoll.h directly is not intended to be safe, > > instead poll.h should be used). > > > > In recent times a lot of code has moved around in IIO and as a result > > often headers have gotten left behind or haven't made the move along > > with the code they were there to support. > > > > I made some decisions to reduce includes. > > > > #include <linux/device.h> > > can be assumed to bring in dev_printk.h and device/bus.h so don't include > > those directly. > > #include <linux/err.h> > > is a good general header to bring in errno.h as well as the various > > PTR_ERR() macros and similar. > > #include <linux/poll.h> > > brings in everything related to polling. > > #include <linux/irq.h> or <linux/interrupt.h> as appropriate will bring > > in irqreturn.h. > > > > (probably some other cases I've forgotten about). > > > > Andy has been working on breaking up some of the headers that tend to > > get included everywhere because they are a pile of unrelated things. > > Some impact of that can be seen in this series. > > > > I would like to move IIO in the right direction even if we then end > > up with some additional churn in future reflecting changes in the headers > > we are using.
