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: v2.9.13~16 X-Git-Url: http://git.liburcu.org/?p=lttng-tools.git;a=commitdiff_plain;h=740656beaad64985f60f9d59876f90dc42784e8b 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.
