...; parameter. Similar use as above. > > * Change the block layer, and several file systems, to use > put_user_page*(). I think we can do this in a simple and better way. We have 5 ITER_* types. Of those ITER_DISCARD as the name suggests never uses pages, so we can skip handling it. ITER_PIPE is rejected ?n the direct I/O path, which leaves us with three. Out of those ITER_BVEC needs a user page reference, so we want 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 sh...

[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). I added a
