But if the binary is stripped i.e. built with the -s flag, then I dont think nm will output anything.

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

dh_strip
DH_STRIP(1) Debhelper DH_STRIP(1)
NAME
dh_strip - strip executables, shared libraries, and some static libraries
SYNOPSIS
dh_strip [debhelperoptions] [-Xitem] [--dbg-package=package] [--keep-debug]
DESCRIPTION
dh_strip is a debhelper program that is responsible for stripping executables, shared libraries, and static libraries that are not used for
debugging.
This program examines your package build directories and works out what to strip on its own. It uses file(1) and file permissions and
filenames to figure out what files are shared libraries (*.so), executable binaries, and static (lib*.a) and debugging libraries (lib*_g.a,
debug/*.so), and strips each as much as is possible. (Which is not at all for debugging libraries.) In general it seems to make very good
guesses, and will do the right thing in almost all cases.
Since it is very hard to automatically guess if a file is a module, and hard to determine how to strip a module, dh_strip does not
currently deal with stripping binary modules such as .o files.
OPTIONS
-Xitem, --exclude=item
Exclude files that contain item anywhere in their filename from being stripped. You may use this option multiple times to build up a
list of things to exclude.
--dbg-package=package
Causes dh_strip to save debug symbols stripped from the packages it acts on as independent files in the package build directory of the
specified debugging package.
For example, if your packages are libfoo and foo and you want to include a foo-dbg package with debugging symbols, use dh_strip
--dbg-package=foo-dbg.
Note that this option behaves significantly different in debhelper compatibility levels 4 and below. Instead of specifying the name of
a debug package to put symbols in, it specifies a package (or packages) which should have separated debug symbols, and the separated
symbols are placed in packages with -dbg added to their name.
-k, --keep-debug
Debug symbols will be retained, but split into an independent file in usr/lib/debug/ in the package build directory. --dbg-package is
easier to use than this option, but this option is more flexible.
NOTES
If the DEB_BUILD_OPTIONS environment variable contains nostrip, nothing will be stripped, in accordance with Debian policy (section 10.1
"Binaries").
