Public bug reported: This issue pops up after updating to the latest tip of LTP test suite (commit 776b57984 "rwtest: Remove df symlink check")
These 2 failures are limited to X-kvm kernel and they're all failing with the same error message, I didn't see this failure on other 4.4 variants (X, X-aws, T-lts-X).
