make includecheck does not work for me. Linux tree is from latest git.

bash-3.2$ pwd
/git/linux-2.6

bash-3.2$ make includecheck
find * \( -name SCCS -o -name BitKeeper -o -name .svn -o -name CVS -o
-name .pc -o -name .hg -o -name .git \) -prune -o \
                -name '*.[hcS]' -type f -print | sort \
                | xargs perl -w scripts/checkincludes.pl
Can't open perl script "scripts/checkincludes.pl": No such file or directory
make[1]: *** [includecheck] Error 123
make: *** [sub-make] Error 2

bash-3.2$ ls scripts/checkincludes.pl

actually, one wonders if there's any value in keeping any references
to other version control systems such as subversion, SCCS, CVS,
mercurial, etc.

It allows people to continue using any of {CVS, SVN, BitKeeper}
for their kernel tree.  The BK kernel tree is still being updated
AFAIK.  (It was last time I looked, about 3 weeks ago.)

What do you mean by "other"?  git doesn't have a monopoly, and the
kernel should support people using a reasonable set of version control
systems.  Supporting VSS would be strange, but nothing wrong with the
set you listed, if people find those systems useful.  It's not like it
amounts to a huge amount of effort to do so.

Lots of people have their working trees in CVS, Subversion, ....
So it probably annoys them and doesn't really buy anything IMHO.

you're right, my mistake, i was just caught up in a git-centered
perspective.

Are you building in a different tree than the source tree? The patch below
fixed it for me.

They are generated binaries that live in the output directory structure.

Thanks!

drivers/scsi/gvp11.c is a false positive, as it includes "gvp11.h" once
without HOSTS_C defined and once with.

drivers/scsi/mvme147.c looks similar, but "mvme147.h" does not check for
HOSTS_C (anymore?).

But both need a cleanup anyway...

When was that added? It's not listed in the 'make help', and I see
there's a versioncheck too that's not reported. Some of these are
actually useful, I wonder what else is lurking in the depths of
undocumented Makefile target land ;-)

trust me, it's not a script i'm particularly proud of:

===========================
#!/bin/sh

DIR=${1-*}              # by default, all directories

for cf in $(find ${DIR} -name *.c) ; do
        echo ${cf}
        grep "#include" $cf | sort | uniq -c | grep -v 1
done | grep -B1 "#include" | grep -v -- "--"
===========================

  on the bright side, it took about 90 seconds to write, but i won't
be winning any awards for style.

  i'll add it to the web page.
