[LTP] [PATCH v6 5/5] ftrace: Remove obsolete shell test files
Praveen K Pandey
praveen@linux.ibm.com
Tue Jun 9 06:16:32 CEST 2026
Remove the old shell-based ftrace test files and helper scripts
that have been converted to C. This includes:
- ftrace_lib.sh (replaced by ftrace_lib.c/h)
- ftrace_stress/*.sh (18 helper scripts, replaced by ftrace_stress_test.c)
The C implementation provides better error handling, uses LTP's
modern test API, and is more maintainable.
