On your admin.py:

class YourInline(admin.TabularInline):
    model = YourInlineModel
    formset = YourInlineFormset

    def get_formset(self, request, obj=None, **kwargs):
        formset = super(YourInline, self).get_formset(request, obj, **kwargs)
        formset.request = request
        return formset

On your forms.py:

class YourInlineFormset(forms.models.BaseInlineFormSet):
    def save_new(self, form, commit=True):
        obj = super(YourInlineFormset, self).save_new(form, commit=False)
        # here you can add anything you need from the request
        obj.user = self.request.user

        if commit:
            obj.save()

        return obj
