btrfs related tests in ubuntu_ecryptfs failed on Precise amd64 / i386

[Po-Hsu Lin]

This issue can be reproduced in 3.13.0-142 in proposed and 3.13.0-141. So it should not be considered as a regression.

We didn't have this issue before, until I'm testing 3.13 Precise LTS kernel on the systems (201307-13930 - i386 and 201308-14073 - amd64) in Cert lab instead of using our regular regression-testing test pool from kernel team this cycle.

All btrfs related tests in ubuntu_ecryptfs failed.

The output is not really helpful, it's just saying that the return value is 1, like:

Verified with older kernel (3.13.0-117-generic) on the same amd64 system and this issue still exist.
