Instead of running the nm output through grep and then running it through awk again, run it directly through awk, and bail of immediately if a non-absolute symbol is found. Also, while we're here, avoid executing the indirect parsing code if no __crc_* symbols are present at all, which shaves around 8-18% off of the run time: % for i in ./lib/modules/*; do \ echo "====== $i ====="; \ diff -u <(find $i | ./find-provides.ksyms.old) <(find $i | ./find-provides.ksyms.new); \ echo old:; find $i | time ./find-provides.ksyms.old > /dev/null; \ echo new:; find $i | time ./find-provides.ksyms.new > /dev/null; \ done ====== ./lib/modules/4.18.0-372.57.1.el8_6.s390x ===== old: ../find-provides.ksyms.old > /dev/null 5.10s user 4.52s system 150% cpu 6.412 total new: ../find-provides.ksyms.new > /dev/null 4.41s user 3.48s system 136% cpu 5.764 total ====== ./lib/modules/4.18.0-372.57.1.el8_6.x86_64 ===== old: ../find-provides.ksyms.old > /dev/null 7.80s user 6.19s system 143% cpu 9.740 total new: ../find-provides.ksyms.new > /dev/null 6.07s user 3.97s system 124% cpu 8.066 total ====== ./lib/modules/5.14.0-284.15.1.el9_2.s390x ===== old: ../find-provides.ksyms.old > /dev/null 5.87s user 4.35s system 143% cpu 7.113 total new: ../find-provides.ksyms.new > /dev/null 5.12s user 3.56s system 132% cpu 6.533 total ====== ./lib/modules/5.14.0-284.15.1.el9_2.x86_64 ===== old: ../find-provides.ksyms.old > /dev/null 8.44s user 6.78s system 144% cpu 10.535 total new: ../find-provides.ksyms.new > /dev/null 6.55s user 4.17s system 123% cpu 8.666 total ====== ./lib/modules/6.4.0-0.rc1.20230511git80e62bc8487b.19.eln126.s390x ===== old: ../find-provides.ksyms.old > /dev/null 5.04s user 3.95s system 145% cpu 6.166 total new: ../find-provides.ksyms.new > /dev/null 4.64s user 3.17s system 136% cpu 5.719 total ====== ./lib/modules/6.4.0-0.rc1.20230511git80e62bc8487b.19.eln126.x86_64 ===== old: ../find-provides.ksyms.old > /dev/null 8.49s user 5.54s system 139% cpu 10.043 total new: ../find-provides.ksyms.new > /dev/null 7.41s user 4.31s system 129% cpu 9.046 total * find-provides.ksyms: Rewrite the "if nm | grep -q; then nm | awk" with straight "nm | awk", update the awk script to return the exit code accordingly, execute indirect symbol parsing only if inderect __crc_* symbols are present. * find-requires.ksyms (all_provides): Likewise.
