2025-01-11selftests/powerpc: Fix argument order to timer_sub()Michael Ellerman
Commit c814bf958926 ("powerpc/selftests: Use timersub() for gettimeofday()"), got the order of arguments to timersub() wrong, leading to a negative time delta being reported, eg: test: gettimeofday tags: git_version:v6.12-rc5-409-gdddf291c3030 time = -3.297781 success: gettimeofday The correct order is minuend, subtrahend, which in this case is end, start.

Move the KEY_PATH variable definition inside the set_user_data function to reduce global variables and improve encapsulation. The KEY_PATH variable is now dynamically created when setting user data.

2025-01-07sched_ext: Add option -l in selftest runner to list all available testsShizhao Chen
The selftest runner currently allows selecting tests via the -t option. This patch adds a new -l option that lists all available tests, providing users with an overview of the tests they can choose from. This enhancement is especially useful for scripting and automation purposes, making it easier to discover and run tests.
