Currently, sparse issues warnings on code using an attribute it doesn't know about. One of the problem with this is that these warnings have no value for the developer, it's just noise for him. At best these warnings tell something about some deficiencies of sparse itself but not about a potential problem with code analyzed. A second problem with this is that sparse release are, alas, less frequent than new attributes are added to GCC. So, avoid the noise by asking sparse to not warn about attributes it doesn't know about.
