As mentioned above, it works only for 16MB HugeTLB page migration on 64K base pages implemented right on the PMD as a single PTE but not for the 16MB HugeTLB page on 4K base pages implemented through huge page directory. As generic VM migrate code does not look into the page table structure when initiating migration of 16MB on 4K it will just fail without stating the reason which might be some times confusing. I can edit the commit message to capture this point if needed. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
