sysfs-tagging.txt: fix pre-kernfs references
- sysfs_dirent is now kernfs_node - see commit 324a56e16e44 ("kernfs: s/sysfs_dirent/kernfs_node/ and rename its friends accordingly") - sysfs_super_info is now kernfs_super_info - see commit c525aaddc366 ("kernfs: s/sysfs/kernfs/ in various data structures") - the 's_' prefix was dropped from various fields - see commit adc5e8b58f48 ("kernfs: drop s_ prefix from kernfs_node members") Signed-off-by: Ulf Magnusson <ulfalizer@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
