ureadahead needs an out-of-tree kernel patch to add trace events for open(), exec() and uselib() syscalls that take file paths, see bug 462111. This needs to be changed to use fanotify() which is available in the standard kernels. However, it needs to be checked whether it's also available on the Ubuntu touch kernels which often ship an ancient 3.4 kernel with Android changes.
