I just released lttng 0.10.0-pre22 for Linux 2.6.24-rc2, which adds support for multiple callbacks connected to a single marker. I make extensive use the kernel RCU mechanism so batch connexion of probes to different markers can be done as quickly as possible, requiring to wait for quiescent state only when necessary. It proves to be important when connecting probes on busy systems, where waiting for ~50 synchronize_sched() could take about 1-2 minutes.
LTTng 0.10.0-pre23 fixes a bug in an inaccurate assumption that a function pointer is always aligned on (at least) 2 bytes boundaries. It's not on some architectures.
