Everyone seems to be hitting this warning, but I can't reproduce it at
all. It came from a bug when I made pointers unsigned...
I though I fixed it in commit 8a9817501654 ("zero_to_err_ptr: fix fall
out from unsigned pointer changes and improve") but now I can't
reproduce it even when I revert that patch.
I'm using a clean smatch clone and a clean kernel clone, but I just
can't trigger false positives. I get valid warnings still but not the
false positives.
Can anyone help me figure this out?
regards,
dan carpenter
