Louis Rilling 420118caa3 configfs: Rework configfs_depend_item() locking and make lockdep happy ... configfs_depend_item() recursively locks all inodes mutex from configfs root to the target item, which makes lockdep unhappy. The purpose of this recursive locking is to ensure that the item tree can be safely parsed and that the target item, if found, is not about to leave. This patch reworks configfs_depend_item() locking using configfs_dirent_lock. Since configfs_dirent_lock protects all changes to the configfs_dirent tree, and protects tagging of items to be removed, this lock can be used instead of the inodes mutex lock chain. This needs that the check for dependents be done atomically with CONFIGFS_USET_DROPPING tagging. Now lockdep looks happy with configfs. [ Lifted the setting of s_type into configfs_new_dirent() to satisfy the atomic setting of CONFIGFS_USET_CREATING -- Joel ] Signed-off-by: Louis Rilling <louis.rilling@kerlabs.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>		16 years ago
