charset="utf-8" There are a couple of things pylint takes issue with: - The "time" import is unused - The import order (iotests should come last) - get_bitmap_hash() doesn't use @self and so should be a function - Semicolons at the end of some lines - Parentheses after "if" - Some lines are too long (80 characters instead of 79) - inject_test_case()'s @name parameter shadows a top-level @name variable - "lambda self: mc(self)" were equivalent to just "mc", but in inject_test_case(), it is not equivalent, so add a comment and disable the warning locally - Always put two empty lines after a function - f'exec: cat > /dev/null' does not need to be an f-string Fix them.
