great work and thanks for sharing it!

I am confused on the differences (computation wise) between this work and FA3 by TriDao. I noticed that FlashMLA doesn't have the up projection matrix multiplies i.e.

Image equations 2 and 5 here. this just makes it similar (functionally) to MHA/GQA, am i missing something?

Thanks.
