From 5d5d568975307877e9195f5305f4240e506a2807 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 3 Apr 2015 15:41:18 -0400 Subject: [PATCH] make new_sync_{read,write}() static All places outside of core VFS that checked ->read and ->write for being NULL or called the methods directly are gone now, so NULL {read,write} with non-NULL {read,write}_iter will do the right thing in all cases.
