This issue ultimately has the same root cause as LP: #1880659, namely that in the 5.6 development cycle, the proc_fs infrastructure was modified to not use the generic file_operations struct and instead use a simplified procfs_ops struct (see d56c0d45f0e27 'proc: decouple proc from VFS with "struct proc_ops"'), which is why this test is failing.

This has been fixed in the qa-regression- testing tree in https:/ /git.launchpad. net/qa- regression- testing/ commit/ ?id=f815e50b3ff d0cacdca98dee62 d324ff1488bcb3
Thanks.
