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
