- mds_reint_create() should take same inode create lock (2926)
- correct journal credits calculated for CANCEL_UNLINK_LOG (2931)
- don't close files for self_export to avoid uninitialized obd (2936)
- - let lustre could be mounted with the same name for node and mds (2939)
-
+ - allow MDS with the same name as client node (2939)
+ - hold dentry reference for closed log files for unlink (2325)
+ - reserve space for all logs during transactions (2059)
+ - don't evict page beyond end of stripe extent (2925)
+ - don't oops on a deleted current working directory (2399)
