From 93265d13ea5c3ec5f61a8009407fbe046ce6b7c0 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 16 Jun 2008 13:46:47 +0200 Subject: [PATCH] sysfs: don't call notify_change sysfs_chmod_file() calls notify_change() to change the permission bits on a sysfs file. Replace with explicit call to sysfs_setattr() and fsnotify_change(). This is equivalent, except that security_inode_setattr() is not called. This function is called by drivers, so the security checks do not make any sense.
