Subject: [PATCH 1/3] export symbol report: overview
Date: Fri, 21 Apr 2006 18:21:45 -0700 (PDT) [thread overview]
Message-ID: <20060422012145.74296470031@localhost> (raw)
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.
