mm: delete unused get_kernel_page()
get_kernel_page() was added in 2012 by [1]. It was used for a while for NFS, but then in 2014, a refactoring [2] removed all callers, and it has apparently not been used since. Remove get_kernel_page() because it has no callers. [1] commit 18022c5d8627 ("mm: add get_kernel_page[s] for pinning of kernel addresses for I/O") [2] commit 91f79c43d1b5 ("new helper: iov_iter_get_pages_alloc()") Link: https://lkml.kernel.org/r/20210729221847.1165665-1-jhubbard@nvidia.com Signed-off-by: John Hubbard <jhubbard@nvidia.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: David Hildenbrand <david@redhat.com> Cc: Mel Gorman <mgorman@suse.de> Cc: Rik van Riel <riel@redhat.com> Cc: David S.
