From 390b421c42c8b749661f018818f1d34f339fc3b2 Mon Sep 17 00:00:00 2001 From: Ulf Magnusson Date: Wed, 2 Sep 2015 14:34:52 +0200 Subject: [PATCH] sysfs.txt: fix pre-kernfs sysfs_dirent reference sysfs_dirent went away when kernfs was extracted from sysfs. The reference to the kobject now lives in a kernfs_node (in the 'priv' member). See commit 324a56e16e44 ("kernfs: s/sysfs_dirent/kernfs_node/ and rename its friends accordingly").
