[PATCH 31/34] nfs: convert put_page() to put_user_page*()

From: <hidden>
Date: 2019-08-02 02:22:07
Also in: amd-gfx, ceph-devel, dri-devel, intel-gfx, kvm, linux-arm-kernel, linux-block, linux-crypto, linux-fsdevel, linux-media, linux-mm, linux-nfs, linux-rdma, linux-xfs, lkml, netdev, sparclinux, xen-devel
Subsystem: filesystems (vfs and infrastructure), nfs, sunrpc, and lockd clients, the rest · Maintainers: Alexander Viro, Christian Brauner, Trond Myklebust, Anna Schumaker, Linus Torvalds

From: John Hubbard <jhubbard@nvidia.com>

For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page() or
release_pages().

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
