From ef79f8e191722dbc1fc33bdfc448f572266c37e9 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 24 Sep 2009 09:34:37 -0600 Subject: [PATCH] cpumask: remove unused mask field from struct irqaction. 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.
