Subject: [PATCH 4/5] staging: erofs: staticize erofs_shrink_count, erofs_shrink_scan
Date: Wed, 16 Jan 2019 16:59:55 +0800 [thread overview]
Message-ID: <20190116085956.21004-4-gaoxiang25@huawei.com> (raw)
In-Reply-To: <20190116085956.21004-1-gaoxiang25@huawei.com>
Move erofs_shrinker_info to utils.c and therefore
no need to globalize erofs_shrink_count and erofs_shrink_scan.
Signed-off-by: Gao Xiang <gaoxiang25@huawei.com>
