Subject: [PATCH 3/3] iova: Stop exporting some more functions
Date: Wed, 9 Dec 2020 23:50:19 +0800 [thread overview]
Message-ID: <1607529019-229549-4-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1607529019-229549-1-git-send-email-john.garry@huawei.com>
The following functions are not referenced outside dma-iommu.c (apart
from iova.c), which can only be built-in:
- init_iova_flush_queue()
- free_iova_fast()
- queue_iova()
- alloc_iova_fast()
So stop exporting them.
