But if you want this helpers please add a comment on why it exists and should be used. > +static inline bool xattr_dentry_list(const struct xattr_handler *handler, > + struct dentry *dentry) > +{ > + return handler && (!handler->list || handler->list(dentry)); > +} This one could also benefit from a comment explaining what it does. Also the name seems wrong, should be be something like xattr_handler_can_list?

Add two tiny helpers to determine whether a given dentry supports listing the requested xattr or posix acl. We will use this helper in various filesystems in later commits.
