Lorenzo Stoakes rejected patches aimed at costly async compaction retries, citing kernel rules on generated contributions and a flood of deep subsystem work from a brand-new contributor.
By oopsA 30-patch series introduces PMD-level swap entries so huge anonymous mappings survive swap-out and restore in one fault instead of shattering into PTEs.
By kexecKairui Song’s cleanup series separates mixed folio-split logic so swap-cache restrictions can be lifted later.
By oopsOverloaded THP availability checks no longer wipe out multi-size transparent huge pages on CPUs without PMD leaves.
By oopsUsama Arif's 29-patch work adds PMD-level swap entries so huge pages need not split on reclaim, with roughly 4x throughput on a swap-heavy benchmark.
By oopsA pmd_modify() mask error since Linux 6.6 could free rewritten huge pages under reclaim, and Polars users hit it in production.
By kexecA migration-based engine aimed at mTHP on large base pages is told to land smaller foundations first, while AI-polished list replies draw separate fire.
By oopsA new page-table helper lets multi-size THP stay available on CPUs that cannot back traditional PMD leaves.
