Ian Kent 0559f63057 kernfs: fix missing kernfs_iattr_rwsem locking ... When the kernfs_iattr_rwsem was introduced a case was missed. The update of the kernfs directory node child count was also protected by the kernfs_rwsem and needs to be included in the change so that the child count (and so the inode n_link attribute) does not change while holding the rwsem for read. Fixes: 9caf696142 ("kernfs: Introduce separate rwsem to protect inode attributes.")
