Title:
  ureadahead does not trace with vanilla kernel

Status in ureadahead package in Ubuntu:
  New

Bug description:
  Using Ubuntu's pre-installed kernel, ureadahead does its job. But
  switching to a newer self- compiled one, no tracing file is created
  and /var/log/upstart/ureadahead.log contains garbage. So I consider it
  related to Bug #1085766.

  Ubuntu 14.04 LTS
  Kernel: 3.15.4
  Kernel config settings: 
  CONFIG_FTRACE=y (and more settings containing "FTRACE")
  CONFIG_DEBUG_FS=y
  ureadahead 0.100.0-16
  Patch installed "0001-trace-add-trace-events-for-open-exec-an.patch" (edited for 3.15.4)
