[PATCH 00/12] block/bio, fs: convert put_page() to put_user_page*()
...nt to call
put_user_page* on it. ITER_BVEC always already has page reference,
which means in the block direct I/O path path we alread don't take
a page reference. We should extent that handling to all other calls
of iov_iter_get_pages / iov_iter_get_pages_alloc. I think we should
just reject ITER_KVEC for direct I/O as well as we have no users and
it is rather pointless. Alternatively if we see a use for it the
callers should always have a life page reference anyway (or might
be on kmalloc memory), so we really should not take a reference either.
In other words: the only time we should ever h...

[PATCH 00/12] block/bio, fs: convert put_page() to put_user_page*()
From: John Hubbard <jhubbard at nvidia.com>
Hi,
This is mostly Jerome's work, converting the block/bio and related areas
to call put_user_page*() instead of put_page(). Because I've changed
Jerome's patches, in some cases significantly, I'd like to get his
feedback before we actually leave him listed as the author (he might
want to disown some or all of these).
