Subject: [PATCH 09/11] fs: remove compat_sys_vmsplice
Date: Mon, 21 Sep 2020 16:34:32 +0200	[thread overview]
Message-ID: <20200921143434.707844-10-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native vmsplice syscall
can be used for the compat case as well.

Subject: [PATCH 09/11] fs: remove compat_sys_vmsplice
Date: Mon, 21 Sep 2020 16:34:32 +0200	[thread overview]
Message-ID: <20200921143434.707844-10-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native vmsplice syscall
can be used for the compat case as well.

Signed-off-by: Christoph Hellwig <hch@lst.de>

Subject: [PATCH 09/11] fs: remove compat_sys_vmsplice
Date: Mon, 21 Sep 2020 16:34:32 +0200	[thread overview]
Message-ID: <20200921143434.707844-10-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native vmsplice syscall
can be used for the compat case as well.

Signed-off-by: Christoph Hellwig <hch@lst.de>
