  "message": "sysfs: add sysfs_dirent-\u003es_parent\n\nAdd sysfs_dirent-\u003es_parent.  With this patch, each sd points to and\nholds a reference to its parent.  This allows walking sysfs tree\nwithout referencing sd-\u003es_dentry which can go away anytime if the user\ndoesn\u0027t control when it\u0027s deleted.\n\nsd-\u003es_parent is initialized and parent is referenced in\nsysfs_attach_dirent().  Reference to parent is released when the sd is\nreleased, so as long as reference to a sd is held, s_parent can be\nfollowed.\n\ndentry walk in sysfs_readdir() is convereted to s_parent walk.\n\nThis will be used to reimplement symlink such that it uses only\nsysfs_dirent tree.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
