| H A D | kernfs-internal.h | diff cf9e5a73 Fri Nov 29 15:18:32 MST 2013 Tejun Heo <tj@kernel.org> sysfs, kernfs: make sysfs_dirent definition public sysfs_dirent includes some information which should be available to kernfs users - the type, flags, name and parent pointer. This patch moves sysfs_dirent definition from kernfs/kernfs-internal.h to include/linux/kernfs.h so that kernfs users can access them. The type part of flags is exported as enum kernfs_node_type, the flags kernfs_node_flag, sysfs_type() and kernfs_enable_ns() are moved to include/linux/kernfs.h and the former is updated to return the enum type. sysfs_dirent->s_parent and ->s_name are marked explicitly as public. This patch doesn't introduce any functional changes. v2: Flags exported too and kernfs_enable_ns() definition moved. v3: While moving kernfs_enable_ns() to include/linux/kernfs.h, v1 and v2 put the definition outside CONFIG_SYSFS replacing the dummy implementation with the actual implementation too. Unfortunately, this can lead to oops when !CONFIG_SYSFS because kernfs_enable_ns() may be called on a NULL @sd and now tries to dereference @sd instead of not doing anything. This issue was reported by Yuanhan Liu.
