In fact this version was written by me, giving you the attribution because I stole a cool idea from you. But none of this actually matters, there's not magic exception just because someone wrote the code. > Then you removed the export talking about the "abuse" of bcachefs using > it. WTF? The random NULL bdev check that breaks the proper splitting. We told told you that's not the way to go, but you just sent it directly to Linus instead of reworking it. And this then got into the way of the rework Keith did to support arbitrarily small memory alignments. Fortunately we could clean this up properly now.
