Subject: To kunmap_atomic or not to kunmap_atomic ?
Date: Thu, 01 Apr 2004 18:30:28 +0200 [thread overview]
Message-ID: <406C43A4.E29F92FB@nospam.org> (raw)
In-Reply-To: Pine.LNX.4.58.0404010734020.18465@build.arklinux.oregonstate.edu
I can see a couple of functions, like
static inline struct mm_struct * ptep_to_mm(pte_t * ptep)
{
struct page * page = kmap_atomic_to_page(ptep);
return (struct mm_struct *) page->mapping;
}
in "rmap.?" without invoking "kunmap_atomic()".
Is it intentional?
What if for an architecture "kunmap_atomic()" is not a no-op ?
Thanks,
Zoltan Menyhart
