From: Andreas Gruenbacher Date: Sun, 15 Jan 2023 16:50:44 +0000 (-0800) Subject: iomap: Rename page_ops to folio_ops X-Git-Tag: Ubuntu-6.5.0-9.9~3304^2 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=471859f57d42537626a56312cfb50cd6acee09ae;p=mirror_ubuntu-kernels.git iomap: Rename page_ops to folio_ops The operations in struct page_ops all operate on folios, so rename struct page_ops to struct folio_ops.
