From a7259df7670240ee03b0cfce8a3e5d3773911e24 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Thu, 2 Sep 2021 15:00:26 -0700 Subject: memblock: make memblock_find_in_range method private There are a lot of uses of memblock_find_in_range() along with memblock_reserve() from the times memblock allocation APIs did not exist. memblock_find_in_range() is the very core of memblock allocations, so any future changes to its internal behaviour would mandate updates of all the users outside memblock. Replace the calls to memblock_find_in_range() with an equivalent calls to memblock_phys_alloc() and memblock_phys_alloc_range() and make memblock_find_in_range() private method of memblock. This simplifies the callers, ensures that (unlikely) errors in memblock_reserve() are handled and improves maintainability of memblock_find_in_range().
