Subject: [PATCH] scripts/checkstack.pl: change min_stack to 512 by default
According to Documentation/process/submit-checklist.rst, checkstack does
not point out problems explicitly, but any one function that uses more
than 512 bytes on the stack is a candidate for change, hence it is better
to omit any stack frame sizes smaller than 512 bytes, just change
min_stack to 512 by default.
