0) Remove fs.h from mm.h. For this,
1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
2) Add back fs.h or less bloated headers (err.h) to files that need it.

As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).

Cross-compile tested without regressions on my two usual configs and (sigh):

Hi Alexey,

Can I do something to help this regression testing?

Please feel free to ask me.

Thanks a lot

Oh, do you need use blackfin toolchain? Actually, it is very simple to
setup it on your machine.
please get the latest binary toolchain here:
http://blackfin.uclinux.org/gf/download/frsrelease/344/3180/blackfin-toolchain-uclinux-SVN.tar.bz2
http://blackfin.uclinux.org/gf/download/frsrelease/344/3181/blackfin-toolchain-linux-uclibc-SVN.tar.bz2

 - untar these 2 tar ball
 - add the path to your environment variables
 - ready to compile the kernel by these blackfin cross toolchain

Need I to generate the patch? I will take a look at the latest git-tree.

Many thanks, we hope you can add our blackfin to your cross-build check.

Best Regards,

it the right way I have no patch.

I will check this on my side ASAP.  But the git-tree did not merge my
"fs.h" header file patch, how could it compiled passed like this?

I just inserted "#include <linux/fs.h> in mm.h as a temporary workaround.
I also had to deselect a few drivers to make it build this far (used defconfig).

Hi, Alexery,

This change breaks m32r, too.
Don't forget updating the other archs, please.

Apologies. I just finished adding m32r to my cross-build setup, so there
shouldn't be any more such breakages.

Actually frv was tested (and patched), just not glued to cross-build

sh ended up breaking all over the place, and sh64 in a few others.
I'll roll the fixes in to my git trees, but here they are for reference.
