From a8adbe378b56acd5945df70753c7e8f6fe223304 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Fri, 17 Dec 2010 08:56:44 +0100 Subject: fs/splice: Pull buf->ops->confirm() from splice_from_pipe actors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch pulls calls to buf->ops->confirm() from all actors passed (also indirectly) to splice_from_pipe_feed(). Is avoiding the call to buf->ops->confirm() while splice()ing to /dev/null is an intentional optimization? No other user does that and this will remove this special case.
