Bug Fixes

Percona Server 5.5.27-28.0 would crash or deadlock in XtraDB buffer pool code. This was caused by incorrect mutex handling in porting of the recently introduced InnoDB code to XtraDB. Bug fixed #1038225 (Laurynas Biveinis).

Variables innodb_adaptive_flushing_method and innodb_flush_neighbor_pages would not correctly translate some values internally. Bug fixed #1039384 (Laurynas Biveinis).

This documentation is developed in Launchpad as part of the Percona Server 5.5.
