Subject: [PATCH v8 01/14] iommufd/fault: Move two fault functions out of the header
Date: Tue, 25 Feb 2025 09:25:29 -0800 [thread overview]
Message-ID: <14a01d676b06dc7c013edba6961a4c1e9503a4e1.1740504232.git.nicolinc@nvidia.com> (raw)
In-Reply-To: <cover.1740504232.git.nicolinc@nvidia.com>
There is no need to keep them in the header. The vEVENTQ version of these
two functions will turn out to be a different implementation and will not
share with this fault version. Thus, move them out of the header.
