From cbb7e577e732f576b9f399bc2600bdc0626c68dc Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 11 Apr 2006 14:57:50 +0200 Subject: [PATCH] splice: pass offset around for ->splice_read() and ->splice_write() We need not use ->f_pos as the offset for the file input/output. If the user passed an offset pointer in through sys_splice(), just use that and leave ->f_pos alone.
