RPMscripts for previous Percona Server version caused installer to fail if there were different
datadiroptions in multiple configuration files. Bug fixed #1201036.

LRUlist mutex in the
I/Ocompletion routine, for the compressed page flush list flushes where it was not necessary. Bug fixed #1181269.
