Subject: [PATCH] Remove fs.h from mm.h
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):
