From 1b0aa4449cb81e0a7d43cb90d03888c23bacc825 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 3 Mar 2022 13:43:29 -0500 Subject: ext4: Call aops write_begin() and write_end() directly pagecache_write_begin() and pagecache_write_end() are now trivial wrappers, so call the aops directly.
