  "message": "sysfs: reimplement symlink using sysfs_dirent tree\n\nsysfs symlink is implemented by referencing dentry and kobject from\nsysfs_dirent - symlink entry references kobject, dentry is used to\nwalk the tree.  This complicates object lifetimes rules and is\ndangerous - for example, there is no way to tell to which module the\ntarget of a symlink belongs and referencing that kobject can make it\nlinger after the module is gone.\n\nThis patch reimplements symlink using only sysfs_dirent tree.  sd for\na symlink points and holds reference to the target sysfs_dirent and\nall walking is done using sysfs_dirent tree.  Simpler and safer.\n\nPlease read the following message for more info.\n\n  http://article.gmane.org/gmane.linux.kernel/510293\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
