Subject: [PATCH 3/6] provide a generic io_syscall6
Date: Thu, 4 Jan 2018 09:03:22 +0100 [thread overview]
Message-ID: <20180104080325.14716-4-hch@lst.de> (raw)
In-Reply-To: <20180104080325.14716-1-hch@lst.de>
This allows to call a 6-argument syscall using the generic syscall()
function from libc. No arch-specific version is specified as it would
be a lot of effort for very little gain.
Signed-off-by: Christoph Hellwig <hch@lst.de>
