@@ -127,7 +127,6 @@ Features:
- kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
- kdbus: we need a way to distuingish messages we got due to monitoring from normal messages, since we want to bind methods only to the latter
- figure out what to do when fields in the kdbus header and in the payload header do not match
- - nameownerchange cannot be properly synthesized since we cannot distuingish messages from kernel when a name changed ownership starter → real from real → starter
- longer term:
* priority queues
* priority inheritance
