I have used to following to see how a new version compares:


k=500;i=0;j=0;for sha in $(git log --no-merges --format=format:"%h" -$k);do let i=$i+1; git show $sha >/tmp/a; clear;echo $i;head -20 /tmp/a; ./scripts/checkpatch.pl --root=. /tmp/a; err=$?; if [ $err != 0 ]; then let j=$j+1;read foo;fi; done;echo Check $i, Bad $j

...
total: 0 errors, 0 warnings, 79 lines checked

/tmp/a has no obvious style problems and is ready for submission.
Check 500, Bad 52
