Description

"job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory"

Just about every sub-test in a pjd test execution failed with that error message: http://qa-proxy.ceph.com/teuthology/teuthology-2014-12-07_23:04:02-fs-next-testing-basic-multi/641512/ This is a new failure we haven't seen before

Going over the recent patches and ceph-qa-suite runs, I'm guessing it's a result of 491da5173fc33fec944865f0e2e9a506ec71fc5b "client: invalidate kernel dentries one by one", but perhaps it's something else.
