before pushing the patch, review it yourself both the small change that you just made and where it stands in the long series of changes or in relation to the change you are going to ammend it to. often it happens that an ammend voids the previously added comments and assumptions in code, so they need to be updated. then question every single line as if it's not your code and then push and ask someone else to review it.
you are responsible for the changes you push therefore you should do the most amount of work to see that it's correct. pushing changes carelessly, expecting someone else to correct you shows how involved you are in the process.
