Subject: [PATCH 5/9] fs: remove various compat readv/writev helpers
Date: Fri, 18 Sep 2020 14:45:29 +0200	[thread overview]
Message-ID: <20200918124533.3487701-6-hch@lst.de> (raw)
In-Reply-To: <20200918124533.3487701-1-hch@lst.de>

Now that import_iovec handles compat iovecs as well, all the duplicated
code in the compat readv/writev helpers is not needed.  Remove them
and switch the compat syscall handlers to use the native helpers.

Subject: [PATCH 5/9] fs: remove various compat readv/writev helpers
Date: Fri, 18 Sep 2020 14:45:29 +0200	[thread overview]
Message-ID: <20200918124533.3487701-6-hch@lst.de> (raw)
In-Reply-To: <20200918124533.3487701-1-hch@lst.de>

Now that import_iovec handles compat iovecs as well, all the duplicated
code in the compat readv/writev helpers is not needed.  Remove them
and switch the compat syscall handlers to use the native helpers.
