Hello,
The aim of this patch series is to improve the resctrl selftest. Without these fixes, some unnecessary processing will be executed and test results will be confusing. There is no behavior change in test themselves.
[patch 1] Make write_schemata() run to set up shemata with 100% allocation on first run in MBM test. [patch 2] The MBA test result message is always output as "ok", make output message to be "not ok" if MBA check result is failed. [patch 3] When a child process is created by fork(), the buffer of the parent process is also copied. Flush the buffer before executing fork(). [patch 4] An error occurs whether in parents process or child process, the parents process always kills child process and runs umount_resctrlfs(), and the child process always waits to be killed by the parent process. [patch 5] If a signal received, to cleanup properly before exiting the parent process, commonize the signal handler registered for CMT/MBM/MBA tests and reuse it in CAT, also unregister the signal handler at the end of each test. [patch 6] Before exiting each test CMT/CAT/MBM/MBA, clear test result files function cat/cmt/mbm/mba_test_cleanup() are called twice. Delete once.
This patch series is based on Linux v6.2-rc7.
A later patch series was picked up by kselftest causing a conflict with this series. Could you please submit a new version that is based on the "next" branch of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git ?
Thank you very much
