Saw this crash on a linux-next pulled yesterday at 2PM EST, kernel dies very early (looks like first time it touches configfs for anything - trying to boot with netconsole enabled caused it to die even faster). I can bisect this if it doesn't immediately ring a bell...
It dies here:
void d_set_d_op(struct dentry *dentry, const struct dentry_operations *op) { BUG_ON(dentry->d_op);
Am guessing configfs passed in a dentry that wasn't filled in enough.
