Subject: vfs: optimize touch_time too fix
From: Hugh Dickins <hugh.dickins@tiscali.co.uk>

Recent mmotms give me WARNING: at fs/namespace.c:612 mntput_no_expire()+...
when unmounting: __mntput()'s WARN_ON(count_mnt_writers(mnt)).

That's because vfs-optimize-touch_time-too.patch inverted the sense
of mnt_want_write_file(), which is error-returning, not a boolean.

Presumably filetime updates went missing too, but I didn't notice those.
