Linus Torvalds 6020c204be Convert much of the page cache to use folios ... This patchset stops just short of actually enabling large folios. It converts everything that I noticed needs to be converted, but there may still be places I've overlooked which still have page size assumptions. The big change here is using large entries in the page cache XArray instead of many small entries. That only affects shmem for now, but it's a pretty big change for shmem since it changes where memory needs to be allocated (at split time instead of insertion). -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEejHryeLBw/spnjHrDpNsjXcpgj4FAmHcraoACgkQDpNsjXcp gj7C3wgAl0cjtdVzTpkLmbnInsicW1m3thnbkSXYbpqRccFjpu2kEBGj31PT+oGz dzgXP7SNZ/VkFT+qWtmHSRF/J41B6f9bFojO81B2aQdpRiziU+5QbSbXbfUjwVhE GJF0WGSJtVqySKynXP/iYTEt2zj6BiVperAwIqzhZpPY7gNoyDgeRD34Xy5bQqdD ey6/Uwkh7oFHLEDcgxsEnyF0tUR3q+gpe5XZW1fb79p3crWw44xATc3UvKv8qCLC Rd4oHmKkOj4MvdiUxJEfXI+XxgrkQ8XRO70B+p6ZljhDaoDZYw7ullxA0gvlSpNX 6pnjSQlKA1VQXsi6PMSt+9vf26XxaQ== =KeYZ -----END PGP SIGNATURE----- Merge tag 'folio-5.17' of git://git.infradead.org/users/willy/pagecache Pull folio conversion updates from Matthew Wilcox: "Convert much of the page cache to use folios This stops just short of actually enabling large folios.
