From 75de46b98dda624397ccb17c106e51f478a79c15 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Mon, 31 May 2010 17:58:02 +1000 Subject: fix setattr error handling in sysfs, configfs sysfs and configfs setattr functions have error cases after the generic inode's attributes have been changed. Fix consistency by changing the generic inode attributes only when it is guaranteed to succeed.
