The first three patches I hope are added into 6.0 before release (and
the one cc:stable gets backported to 5.19).
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.
