My focus this round has been on shmem. I believe it is now fully
converted to folios. Of course, shmem interacts with a lot of the swap
cache and other parts of the kernel, so there are patches all over the MM.
This patch series survives a round of xfstests on tmpfs, which is nice,
but hardly an exhaustive test. Hugh was nice enough to run a round of
tests on it and found a bug which is fixed in this edition.
Also new in this edition is the addition of
mm: Convert lock_page_or_retry() to folio_lock_or_retry()
which I inadvertently left out of the first round of patches. I adjusted
the shmem_replace_page() patch to apply on top of 76d36dea0269.
