Subject: [PATCH] mm/gup_benchmark: mark gup_benchmark_init as __init function
Date: Tue, 3 Nov 2020 21:10:16 +1300 [thread overview]
Message-ID: <20201103081016.16532-1-song.bao.hua@hisilicon.com> (raw)
gup_benchmark_init() is only called during initialization, mark it as
__init to save some memory.
