Matthew Wilcox (Oracle) 49fd9b6df5 mm/vmscan: fix a lot of comments 
Patch series "MM folio changes for 6.1", v2.

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.


This patch (of 57):

A lot of comments mention pages when they should say folios.
Fix them up.
