Why can't you do this
- resolve rules (not for single process, but for all processes) for
said path and tag dentry (seem to already have a hook)
Because it doesn't work http://kerneltrap.org/mailarchive/linux-fsdevel/2007/6/8/319446
Quick summary: The difference between the pathname model and the label model is dynamism. The accessi really is determined by the pathname to the file that you used to access the file. If you try to compute access based on attributes tagged onto the file, then you have to re-compute those attributes every time someone renames a file.
ok. simple question then so why not just recompute them every every rename? are rename's that common relative to all other file operations where we care?
