Subject: Re: [PATCH] sparse: use force attribute for fmode_t casts

Please just use __FMODE_NONOTIFY instead, which might be a bit misnamed,
but was added exactly for this kind of use.

And remember once more:  __force casts are a massive code smell.  Never
add them before thinking hard about them and adding a comment explaining
why they can't be avoided, preferably in a dedicated helper.
