snprintf() returns the would-be-filled size when the string overflows the given buffer size, hence using this value may result in a buffer overflow (although it's unrealistic).

unrealistic == impossible

So why make this change at all?

This patch replaces it with a safer version, scnprintf() for papering over such a potential issue.

Don't "paper over", actually fix real things.

No, this is not a "fix".

Also please do not wrap lines of fixes tags.

thanks,
