From: Mathieu Desnoyers Date: Thu, 23 May 2019 16:56:57 +0000 (-0400) Subject: Fix: initialize syscall table when kernel tracer is lazily initialized X-Git-Tag: v2.10.8~27 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=b6d6994637efb90c3a237e8f3be533c4d9484bb5;p=lttng-tools.git Fix: initialize syscall table when kernel tracer is lazily initialized How to reproduce: start lttng-sessiond while lttng-modules are not installed, then install lttng-modules. Then issue "lttng list --syscall -k". It will show an empty syscall list because the system call list has not been initialized.
