Btw, the calling conventions here also seems fairly ugly.
Instead of the optional dentry parameter I'd have a audit_copy_inode
that takes just the name and the inode, and an optional direct call
to audit_copy_fcaps for those callers that have a dentry. That would
also allow removing the branch for the dentry == NULL case in
audit_copy_fcaps.
