OK, so there are at least four phases of this patch set which are distinct to me. 1. Prep work that can go upstream now 2. Making the page cache able to hold compound pages 3. Making thp-cache work with ramfs 4. Making mmap() work with thp-cache (1) needs to go upstream now. (2) and (3) are related and should go upstream together. There should be enough performance benefits from this alone to let them get merged. (4) has lot of the code complexity, and is certainly required... eventually. I think you should stop for the _moment_ posting things in this category and wait until you get the other stuff merged. Go ahead and keep it in your git tree for toying around with, but don't try to get it merged until parts 1-3 are in. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
