[lttng-dev] Mariadb+LTTng 2.x

[Yang Wang]

It seems not this compatibility problem. I have removed all ust1.0 stuffs in the instrumented Mariadb code and
replaced with lttng-ust 2.x say, tracepoint statements, trancepoint provider files, probes files and use the lib -llttng-ust instead of -lust. Anything I missed?


Is "libust[7848/7853]: " reported from lttng-tools 2.0? Actually, this is printed from

lttng-ust-2.1.2

Thanks

Yang

lttng-ust 2.1 is not compatible with lttng-tools 2.0.

2.1 with 2.1, 2.0 with 2.0.

Thanks,

Mathieu
