There are just too many commits to SRU them all for this bug. There are two which were specifically listed for this issue, however the first cannot be useful, and the second doesn't apply to the code (which didn't yet use direct_io)
So I'm afraid we have to debug this from scratch on vivid. I've still not managed to reproduce this myself. Can you please show which files you can reproduce this with, exactly what the error is, and perhaps a gdb backtrace of lxcfs at that point?
