Subject: [PATCH v2 2/5] kexec_file: Make locate_mem_hole_callback global
Date: Mon, 31 May 2021 10:57:17 +0100	[thread overview]
Message-ID: <20210531095720.77469-3-maz@kernel.org> (raw)
In-Reply-To: <20210531095720.77469-1-maz@kernel.org>

In order for architectures to make use of locate_mem_hole_callback()
and avoid reinventing a square wheel, make this function global
and rename it to kexec_locate_mem_hole_callback() to match the
other global kexec symbols.
