So, I'm sending a followup patch that makes it a lot better by using one perl thread per CPU thread. Before such patch, running this command: $ /usr/bin/time --format='%C took %e seconds' ./scripts/check_docs_external_symbols drivers/gpu/drm/ It takes: ./scripts/check_docs_external_symbols drivers/gpu/drm/ took 1218.96 seconds After the patch: ./scripts/check_docs_external_symbols drivers/gpu/drm/ took 102.04 seconds measured on a machine with a machine with a Xeon(R) W-2133 CPU @ 3.60GHz (12 CPU threads), with normal HDD. > Suggested-by: Matthew Wilcox <willy@xxxxxxxxxxxxx> > Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx> Thanks, Mauro
