From a35eb41519ab8db90e87d375ee9362d6e080ca4c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 3 Oct 2016 09:11:51 -0700 Subject: xfs: simulate per-AG reservations being critically low Create an error injection point that enables us to simulate being critically low on per-AG block reservations. This should enable us to simulate this specific ENOSPC condition so that we can test falling back to a regular file copy. Signed-off-by: Darrick J.
