From: <hidden>

Also in:
amd-gfx, ceph-devel, dri-devel, intel-gfx, kvm, linux-arm-kernel, linux-block, linux-crypto, linux-fbdev, linux-fsdevel, linux-media, linux-mm, linux-nfs, linux-rdma, linux-xfs, lkml, sparclinux, xen-devel
Subsystem:
performance events subsystem, the rest · Maintainers:
Peter Zijlstra, Ingo Molnar, Arnaldo Carvalho de Melo, Namhyung Kim, 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").
