 /*
- * FIXME before releasing in RHEL5 (Heinz Mauelshagen):
- *
- * o symbols naming consistency
- *
- * Likely after 5.3:
- * o integrate code with dmraid package
- * o support metadata updates
- * o use libsysfs rather than duplicated code to access sysfs
- * o remove any limitations to SATA, because dmraid must be device agnostic;
- *   ie. the devices being registered with dmeventd have to be derived from
- *   libdmraid metadata discovery; this essentially means a rewrite!
- *
  * FIXED:
- * o stremaline event processing functions
+ * o streamline event processing functions
  * o register/event processing major:minor usage concept
  * o cover error paths
  * o locking race vs. registration in event processing
