[PATCH 23/28] mm: remove __vmalloc_node_flags_caller
From: Christoph Hellwig <hch@lst.de>
Date: 2020-04-08 12:01:45
Also in:
bpf, linux-arch, linux-arm-kernel, linux-hyperv, linux-iommu, linux-mm, linux-s390, lkml
Subsystem:
bpf [core], bpf [general] (safe dynamic programs and tools), memory management, memory management - core, memory mapping, the rest, vmalloc · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Andrew Morton, David Hildenbrand, Liam R. Howlett, Lorenzo Stoakes, Linus Torvalds, Uladzislau Rezki
Just use __vmalloc_node instead which gets and extra argument. To be able to to use __vmalloc_node in all caller make it available outside of vmalloc and implement it in nommu.c.
