Tejun Heo d911d98748 kernfs: make kernfs_notify() trigger inotify events too ... kernfs_notify() is used to indicate either new data is available or the content of a file has changed. It currently only triggers poll which may not be the most convenient to monitor especially when there are a lot to monitor. Let's hook it up to fsnotify too so that the events can be monitored via inotify too. fsnotify_modify() requires file * but kernfs_notify() doesn't have any specific file associated; however, we can walk all super_blocks associated with a kernfs_root and as kernfs always associate one ino with inode and one dentry with an inode, it's trivial to look up the dentry associated with a given kernfs_node. As any active monitor would pin dentry, just looking up existing dentry is enough. This patch looks up the dentry associated with the specified kernfs_node and generates events equivalent to fsnotify_modify(). Note that as fsnotify doesn't provide fsnotify_modify() equivalent which can be called with dentry, kernfs_notify() directly calls fsnotify_parent() and fsnotify(). It might be better to add a wrapper in fsnotify.h instead.
