From 4c6974f51a981d14f13e36049d6307d3bcda550e Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 7 Nov 2009 23:27:02 -0800 Subject: [PATCH] sysfs: Simplify sysfs_chmod_file semantics Currently every caller of sysfs_chmod_file happens at either file creation time to set a non-default mode or in response to a specific user requested space change in policy. Making timestamps of when the chmod happens and notification of a file changing mode uninteresting. Remove the unnecessary time stamp and filesystem change notification, and removes the last of the explicit inotify and donitfy support from sysfs.
