Hi, Davem & Jakub & Paolo It seems the state of this patchset is changed to 'Deferred' in the patchwork, as the info regarding the state in 'Documentation/process/ maintainer-netdev.rst': Deferred patch needs to be reposted later, usually due to dependency or because it was posted for a closed tree Obviously it was not the a closed tree reason here, I guess it was the dependency reason casuing the 'Deferred' here? I am not sure if I understand what sort of dependency this patchset is running into? It would be good to mention what need to be done avoid the kind of dependency too. Hi, Alexander The v13 mainly address your comments about the page_fage_test module. It seems the your main comment about this patchset is about the new API naming now, and it seems there was no feedback in previous version for about a week: https://lore.kernel.org/all/ca6be29e-ab53-4673-9624-90d41616a154@huawei.com/ If there is still disagreement about the new API naming or other things, it would be good to continue the discussion, so that we can have better understanding of each other's main concern and better idea might come up too, like the discussion about new layout for 'struct page_frag_cache' and the new refactoring in patch 8. >
