Subject: [PATCH 1/5] arm64: rename defer_reserve_crashkernel() to have_zone_dma()
Date: Fri, 19 Aug 2022 07:11:52 +0300 [thread overview]
Message-ID: <20220819041156.873873-2-rppt@kernel.org> (raw)
In-Reply-To: <20220819041156.873873-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
The new name better describes what the function does and does not
restrict its use to crash kernel reservations.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
