From 8d0207652cbe27d1f962050737848e5ad4671958 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 5 Apr 2014 04:27:08 -0400 Subject: ->splice_write() via ->write_iter() iter_file_splice_write() - a ->splice_write() instance that gathers the pipe buffers, builds a bio_vec-based iov_iter covering those and feeds it to ->write_iter(). A bunch of simple cases coverted to that...
