Oh, I see what you mean now. I guess I did try to filter out comments and
forgot that I did that. I wrote this patch over a month ago, even
though I only sent it out for the first time this week.
When I remove the code that filters out comments, the following lines
get flagged:
../lib/random.c:34: * We use this PRNG instead of libc's rand() because
rand() varies in quality
../lib/util.c:649: * similar to the POSIX dirname() function but
thread-safe. */
../lib/util.c:667: * similar to the POSIX basename() function but
thread-safe. */
../ovsdb/ovsdb-client.c:704: * going to strtok() it and that's
risky with literal "". */
See above for list of calls to functions that are
blacklisted due to thread safety issues
I think that these comments are valuable enough that I don't want to
delete or mangle them. What do you think?
Thanks,
Ben.
