From 2046fd1873886e8c774d7c1b0961624c164e7db2 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Tue, 15 Oct 2013 18:45:17 -0500 Subject: ext3: Count journal as bsddf overhead in ext3_statfs ext4 counts journal space as bsddf overhead, but ext3 does not. For some reason when I patched ext4 I thought I should leave ext3 alone, but frankly it makes more sense to fix it, I think. Otherwise we get inconsistent behavior from ext3 under ext3.ko, and ext3 under ext4.ko, which is not at all desirable... This is testable by xfstests shared/289, though it will need modification because it currently special-cases ext3.
