Regression test case for commit: 437a255 xfs: fix direct IO nested transaction deadlock. Signed-off-by: Eryu Guan <eguan@xxxxxxxxxx> --- v3: 1. rename TESTDIR to STRESS_DIR 2. decrease variable by using "let" 3. call wait instead of sync after killing all fsstress processes 4. rebase on top of master v2: 1. drop generic freeze vs fsstress test, 068 has done this 2. remove unnecessary _scratch_unmount 3. rm $seq.full before _scratch_mkfs_xfs 4. remove unnecessary sleep 5. remove unnecessary output 6. run fixed number(10) of iterations of freeze/thaw cycles 7. remove from dangerous group 295 | 88 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 295.out | 3 +++ group | 1 + 3 files changed, 92 insertions(+) create mode 100644 295 create mode 100644 295.out diff --git a/295 b/295 new file mode 100644 index 0000000..57aa63c --- /dev/null +++ b/295 @@ -0,0 +1,88 @@ +#! /bin/bash +# FS QA Test No. 295 +# +# Test freeze/unfreeze file system randomly under fsstress +# Regression test for commit: +# 437a255 xfs: fix direct IO nested transaction deadlock. +# +#----------------------------------------------------------------------- +# Copyright (c) 2013 Red Hat, Inc.
