BTW, it is strange I do not see such compile warning here :(

This was a Smatch static checker warning, not a regular build
warning.

Dear Dan

Thanks for introducing this valuable tool.
Have download from git://repo.or.cz/smatch.git

When trying use this tool, could get some warning,
make CHECK="~/bin/smatch -p=kernel --no-data" C=1 | tee warns.txt

Also some strange warning, like "SQL error #2: no such table:
caller_info", is it ignored?

Oops.  I'll fix that.  The problem is that I don't normally test with
--no-data.  Sorry about that.

Besides, when test this case for check smatch setting.
Still not reproduce the issue, should be not config correct?

This warning requires that the cross function database be set up.

regards,
dan carpenter
