From 6818173bd658439b83896a2a7586f64ab51bf29c Mon Sep 17 00:00:00 2001 From: Miklos Szeredi <miklos@szeredi.hu> Date: Thu, 7 May 2009 15:37:36 +0200 Subject: splice: implement default splice_read method If f_op->splice_read() is not implemented, fall back to a plain read. Use vfs_readv() to read into previously allocated pages. This will allow splice and functions using splice, such as the loop device, to work on all filesystems. This includes "direct_io" files in fuse which bypass the page cache.
