From 88e0387769c4bc36c93d25329f6151fb3d6474b2 Mon Sep 17 00:00:00 2001 From: Eric Whitney Date: Mon, 14 Nov 2016 21:48:35 -0500 Subject: [PATCH] ext4: allow inode expansion for nojournal file systems Runs of xfstest ext4/022 on nojournal file systems result in failures because the inodes of some of its test files do not expand as expected. The cause is a conditional in ext4_mark_inode_dirty() that prevents inode expansion unless the test file system has a journal. Remove this unnecessary restriction.
