From f06925c7394236d769c788940c9a7b85dbe4c40c Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Sun, 20 May 2018 22:49:54 -0400 Subject: [PATCH] ext4: report delalloc reserve as non-free in statfs for project quota This reserved space isn't committed yet but cannot be used for allocations. For userspace it has no difference from used space. XFS already does this.
