[PATCH v3 21/26] mm: numa_memblks: make several functions and variables static

Mike Rapoport
2024-08-01T06:20:43Z

From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>

Make functions and variables that are exclusively used by numa_memblks
static.

Move numa_nodemask_from_meminfo() before its callers to avoid forward
declaration.

Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org>
Tested-by: Zi Yan <ziy@nvidia.com> # for x86_64 and arm64
