Revision 64c6d8ed4c55f0a99b1b81558851da80c8d58244 authored by Miklos Szeredi on 17 January 2006, 06:14:42 UTC, committed by Linus Torvalds on 17 January 2006, 07:15:31 UTC
Add possibility for requests to run asynchronously and call an 'end' callback when finished. With this, the special handling of the INIT and RELEASE requests can be cleaned up too.
