[PATCH v3 09/17] memblock: make memblock_debug and related functionality private
From: Mike Rapoport <rppt@kernel.org>
Date: 2020-08-18 15:19:08
Also in:
linux-arm-kernel, linux-iommu, linux-mips, linux-mm, linux-riscv, linux-s390, linux-sh, linuxppc-dev, lkml, sparclinux
Subsystem:
memblock and memory management initialization, memory management, s390 architecture, the rest · Maintainers:
Mike Rapoport, Andrew Morton, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Linus Torvalds
From: Mike Rapoport <redacted> The only user of memblock_dbg() outside memblock was s390 setup code and it is converted to use pr_debug() instead. This allows to stop exposing memblock_debug and memblock_dbg() to the rest of the kernel.
