From ccf953d8f3d68e85e577e843fdcde8872b0a9769 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 10 Mar 2021 18:55:30 +0000 Subject: fb_defio: Remove custom address_space_operations There's no need to give the page an address_space. Leaving the page->mapping as NULL will cause the VM to handle set_page_dirty() the same way that it's handled now, and that was the only reason to set the address_space in the first place.
