[kernelnewbies]a question about checkpatch.pl

[lx]

hi all:
I used the script of checkpatch.pl, but some error messages appeared.
##########################################
[root at localhost kernel_test]# perl checkpatch.pl -f task_01.c
Nested quantifiers in regex; marked by <-- HERE in m/(\((?:[^\(\)]++ <--
HERE |(?-1))*\))/@checkpatch.pl line 444.
##########################################
This is something with checkpatch.pl ? How to fix it.

Thank you.

I see two problems:

1 - You are running as root. This do not cause the error message but
it is way too dangerous. Don't compile, and test as root.

2 - The correct way of invoking checkpatch.pl is from the top-level
dir. of a kernel tree. Example:
cd /path/to/linux/source
./scripts/checkpatch.pl -f /path/to/task_01.c
