[PATCH 1/3] export symbol report: overview

From: Ram Pai
Date: Fri Apr 21 2006 - 21:22:19 EST


This patch series enables on-demand report generation of export symbol usage by
inkernel modules.

A report generated by executing
make allmodconfig
make exportcheck
is available at http://www.sudhaa.com/~ram/misc/new_export_report.txt

The same report can also be generated by executing from the top level
directory:
perl scripts/export_report.pl

This report lists:
1. the usage count of all exported symbols by in-kernel modules.
2. For each in-kernel module lists
a) the in-kernel modules it depend on.
b) list of exported symbols from that in-kernel modules it depend on.

Highlights:
On x86 architecture
(1) 880 exported symbols not used by any in-kernel modules.
(2) 1792 exported symbols used only once.

Thanks to Adrian Bunk, Arjan, Sam Ravnborg, Dagfinn Ilmari for their
valuable comments. All comments have been incorporated.
