AFAIKS, you need one such cookie for each time the > file has been open(2)ed via NFS, and that gets ugly. The 'struct file' is allocated when the file is opened, so it is not shared among users. Each user will therefore be able to cache his/her own permissions. This is why I want to pass the file structure rather than the 'dentry' structure to the readpage/writepage. The latter is common to all users of the file, and can therefore not be used to pass user/process-specific information.
Cheers, Trond
