* export_report: use warn() to issue WARNING, so they go to stderrJim Cromie2011-05-241-1/+7
| | | | | | | | | | Also count CONFIG_MODVERSIONS warnings, and print a NOTE at start of SECTION 2 if any were issued. Section 2 will be empty if the build is lacking this CONFIG_ item, and user may have missed the warnings, as they're off screen.

* export_report: sort SECTION 2 outputJim Cromie2011-05-241-3/+5
| | | | | | | | | | | | Sort SECTION 2 modules by name. Within those module listings, sort the symbol providers by name, and remove the count, as it is misleading; its the kernel-wide count of uses of that symbol, not the count pertaining to the module being outlined. (this can be seen by grepping the output for a single symbol). The count is still used to sort the symbols.

* export_report: do collectcfiles work in perl itselfJim Cromie2011-05-241-2/+8
| | | | | | | | | | | | | | | | | | | | | | | Avoid spawning a shell pipeline doing cat, grep, sed, and do it all inside perl. The <*.c> globbing construct works at least as far back as 5.8.9 Note that this is not just an optimization; the sed command in the pipeline was unterminated, due to lack of escape on the end-of-line (\$) in the regex, resulting in this: $ perl ../linux-2.6/scripts/export_report.pl > /dev/null sed: -e expression #1, char 5: unterminated `s' command sh: .mod.c/: not found Comments on an earlier patch sought an all-perl implementation.

* export_report: fix perl warningsStephen Hemminger2010-03-071-17/+20
| | | | | | | | | | | Use local file handles, use three argument open. Don't modify arguments in perl grep (use sed instead) Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: WANG Cong <amwang@redhat.com> Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
