You are using a very odd meaning of the word "logically", then. Note that inotify does *not* work on NFS, no matter what vfs_unlink() would do. Simply because files are removed on server, not in VFS. And server does not notify clients of such removals. Ergo, any software that relies on inotify delivering notifications of files being removed is broken on NFS. That has nothing whatsoever to the layer in kernel where it's handled; the information asked for is simply not available to client. Period. Incidentally, inotify does not work on a bunch of local filesystems, starting with procfs. And won't work, unless you are seriously proposing to generate events on things like open()/dup2()/etc. In this case we might very well have objects appearing and disappearing without ever having had a dentry. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
