Yep, it is definitely a LOT faster. Running on top 10 commits on main tree
with old and new script:
$ time ./devtools/checkpatches.sh -n10
10/10 valid patches
real 0m32.570s
user 0m30.517s
sys 0m2.256s
$ time ./devtools/dpdk-checkpatch.py -n10
10/10 valid patches
real 0m0.255s
user 0m0.214s
sys 0m0.040s
32.5 seconds down to a quarter of a second is a massive gain. Looking
forward to switching script for checking patches in future!
