Module Name: src
Committed By: riastradh
Date: Sun Apr 30 08:46:03 UTC 2023
Modified Files:
src/sys/sys: sdt.h
Log Message:
sys/sdt.h: Make sure SDT_PROBE*, DTRACE_PROBE* compile the arguments.
This way there's no need to fuss around with conditional declarations
and assignments in the callers to avoid `variable set but not used'
errors in builds without KDTRACE_HOOKS.
