Subject: [GIT PULL] ktest: Update for v6.15


Linus,

ktest update for v6.15:

- Fix failure of directory of log file not existing

  If a LOG_FILE option is set for ktest to log its messages, and the
  directory path does not exist. Then ktest fails. Have ktest attempt
  to create the directory where the log file exists and if that succeeds
  continue on testing.

    ktest: Fix Test Failures Due to Missing LOG_FILE Directories
    
    Handle missing parent directories for LOG_FILE path to prevent test
    failures. If the parent directories don't exist, create them to ensure
    the tests proceed successfully.
