[PATCH] configfs+dlm: Rename config_group_find_obj and state semantics clearly
Configfs being based upon sysfs code, config_group_find_obj() is probably so named because of the similar kset_find_obj() in sysfs. However, "kobject"s in sysfs become "config_item"s in configfs, so let's call it config_group_find_item() instead, for sake of uniformity, and make corresponding change in the users of this function. BTW a crucial difference between kset_find_obj and config_group_find_item is in locking expectations. kset_find_obj does its locking by itself, but config_group_find_item expects the *caller* to do the locking. The reason for this: kset's have their own locks, config_group's don't but instead rely on the subsystem mutex. And, subsystem needn't necessarily be around when config_group_find_item() is called. So let's state these locking semantics explicitly, and rectify the comment, otherwise bugs could continue to occur in future, as they did in the past (refer commit d82b8191e238 in gfs2-2.6-fixes.git).
