I understand that this code is trying to invalidate the directory dentries here. However, I just found that the directory we get at this point is the filesystem root directory, and not the directory we're trying to unlock. So, I still don't fully understand the issue I'm seeing, but I believe the code above is assuming 'ci' is the inode being unlocked, which isn't correct. (Note: I haven't checked if there are other ioctls getting the FS root.) Cheers, -- Luis
