From b7e4a3720d50f4b41cd8198e24fccc60810487b9 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 2 Feb 2021 16:03:11 +0800 Subject: [PATCH] f2fs: relocate inline conversion from mmap() to mkwrite() If there is page fault only for read case on inline inode, we don't need to convert inline inode, instead, let's do conversion for write case.
