From: Su Yue <Damenly_Su@xxxxxxx>
The 034 test may fail to mount, and dmesg says open_ctree() failed due
to device missing.
The partly work flow is
step1 loop1 = losetup image1
step2 loop2 = losetup image2
setp3 mount loop1
The dmesg says the loop2 device is missing.
It's possible and known that while step3 is in open_ctree() and
fs_devices->opened is nonzero, loop2 device has not been added into the
fs_devces. Then read_one_chunk() reports that loop2 is missing.
The solution for this test is try to mount loop2 if loop mount failed.
