New Revision: 39281
Changeset: http://dev.haiku-os.org/changeset/39281
Modified:
haiku/trunk/src/add-ons/kernel/file_systems/bfs/Index.cpp
Log:
* Got rid of the type == 0 feature in Update(); it does not really serve any
purpose anymore, and was just confusing.
* Minor cleanup.
Modified: haiku/trunk/src/add-ons/kernel/file_systems/bfs/Index.cpp

If the method returns B_BAD_INDEX, it means the index couldn't be found

the most common reason will be that the index doesn't exist.
You may not want to let the whole transaction fail because of that.
