Message-Id: <1181631495561-git-send-email-jens.axboe@oracle.com>
Date: Tue, 12 Jun 2007 08:58:00 +0200
From: Jens Axboe <jens.axboe@...cle.com>
To: linux-kernel@...r.kernel.org
Cc: Jens Axboe <jens.axboe@...cle.com>
Subject: [PATCH 4/18] sendfile: remove .sendfile from filesystems that use generic_file_sendfile()
They can use generic_file_splice_read() instead. Since sys_sendfile() now
prefers that, there should be no change in behaviour.
Signed-off-by: Jens Axboe <jens.axboe@...cle.com>
