Hi Jan,
Smatch complains when you pass positive numbers to ERR_PTR(). There
is a warning triggered in iref_to_path().
fs/btrfs/backref.c +920 iref_to_path()
918
919 if (ret)
920 return ERR_PTR(ret);
^^^
"ret" can be either a negative error code, zero, or one here.
921
I looked at the code, but couldn't tell if it was intentional or not.
It really is pretty unusual to do that, so maybe there should be a
comment or something.
regards,
dan carpenter
