Subject: Remove fs.h from mm.h
X-Git-Tag: v2.6.23-rc2~165
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=4e950f6f0189f65f8bf069cf2272649ef418f5e4;p=linux-2.6-omap-h63xx.git

Remove fs.h from mm.h

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):
