Subject: Re: [PATCH] strstrip incorrectly marked __must_check

Hi,

I have several places in my code where the new __must_check of strstrip
will introduce unnecessary dummy variables to avoid the warnings.

Therefore I would like to have the suggested new strim() or
strstip_tail() function. Any chance to have this upstream soon?

Michael
