From 56a3959a96f1b5e046b3760778fd34b4911d0516 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 27 Sep 2013 13:55:37 +0000 Subject: [PATCH] xfstests: btrfs/015: add a regression test for snapshot creation We had a regression where you couldn't snapshot a file system if you mounted it ro and then remounted it rw. This is a test that does just that to make sure we don't have this problem again. I ran the test without the fix and it blew up, and then applied the fix and verified that it passed.
