Hi Sean, I do see your point. But TBH I'm unsure which way to go on this one.

Is this written down anywhere? I couldn't find it in Documentation/process... --Sean

Generally, it should be: #include <linux/foo.h> #include <linux/bar.h> #include <asm/baz.h> #include <asm/quux.h> #include "local.h" Some drivers do this a different way with a single local.h that includes all necessary includes. Also if <linux/foo.h> and <asm/foo.h> both exist, you should include <linux/foo.h> (which almost certainly includes <asm/foo.h>)

Patch to documentation, checkpatch or both :)

Usually <asm/foo.h> should not be included directly, except for a few exceptions like <asm/irq.h>. Witness e.g. the (violated a lot) comment at the top of include/linux/irq.h: /* * Please do not include this file in generic code. There is currently * no requirement for any architecture to implement anything held * within this file. * * Thanks. --rmk */ Gr{oetje,eeting}s, Geert

A recent rearrangement of includes has lead to a problem on m68k as flagged by the kernel test robot. Resolve this by moving the block asm includes to below linux includes. A side effect i that non-Sparc asm includes are now immediately before Sparc asm includes, which seems nice. Using sparse v0.6.4 I was able to reproduce this problem as follows using the config provided by the kernel test robot: $ wget https://download.01.org/0day-ci/archive/20230404/202304041748.0sQc4K4l-lkp@intel.com/config $ cp config .config $ make ARCH=m68k oldconfig $ make ARCH=m68k C=2 M=drivers/net/ethernet/sun CC [M] drivers/net/ethernet/sun/sunhme.o In file included from drivers/net/ethernet/sun/sunhme.c:19: ./arch/m68k/include/asm/irq.h:78:11: error: expected ‘;’ before ‘void’ 78 | asmlinkage void do_IRQ(int irq, struct pt_regs *regs); | ^~~~~ | ; ./arch/m68k/include/asm/irq.h:78:40: warning: ‘struct pt_regs’ declared inside parameter list will not be visible outside of this definition or declaration 78 | asmlinkage void do_IRQ(int irq, struct pt_regs *regs); | ^~~~~~~ Compile tested only.
