Message-Id: <20090612132602.DDCACDDDE1@ozlabs.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Up until 1.1.83, the primitive human tribes used struct sigaction for interrupts. The sa_mask field was overloaded to hold a pointer to the name. When someone created the new "struct irqaction" they carried across the "mask" field as a kind of ancestor worship: the fact that it was unused makes clear its spiritual significance.
