I believe the sizeof(attr) should be in fact sizeof(*attr), fortunately
the current code works because sizeof(struct attribute **) is the same
as sizeof(struct attribute *) for x86.
Thanks, kbuild also reported it and I just pushed a fix.
Out of curiosity, there are platforms where size of pointer is different
from the size of a pointer to a pointer?
