Yup, I think I like that plan. One thing that may be interesting (I certainly think it migth be), would be to add a "struct user_struct *" pointer to the vfs_cred as well. This is because I'd just _love_ to have that "user_struct" fed down to the VFS layer, since I think that is where we may some day want to put things like user-supplied cryptographic keys etc. The advantage of "struct user_struct" (as opposed to just a uid_t) is that it can have information that lives for the whole duration of a login, and it's really the only kind of data structure in the kernel that can track that kind of information. > > (I would suggest calling the FS credentials "struct vfs_cred", > > while the regular user credentials might just be "struct cred". > > Other suggestions?) > > I'm fine about 'vfs_cred', but how about 'struct task_cred' instead > for the second? Sounds fine to me.
