I wasn't thinking straight yesterday - the real fix is to just do a "d_revalidate()". It's literally why that thing exists: check whether a dentry is still valid. In fact, that trivially gets rid of the 'events' subdirectory issues too, so we can stop doing that horrendous simple_recursive_removal() too. Let me reboot into the trivial fix. I just needed to think about this the right way. None of this is anything that the VFS layer has any problems with. Linus
