Re: [Crash-utility] [PATCH] Display "irqaction mask" only if available

Display "irqaction mask" only if available The member "mask" has been removed from "struct irqaction" in the kernel per commit ef79f8e191722dbc1fc33bdfc448f572266c37e9 Author: Rusty Russell <rusty(a)rustcorp.com.au&gt; Date: Thu Sep 24 09:34:37 2009 -0600 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. Signed-off-by: Rusty Russell <rusty(a)rustcorp.com.au&gt; This patch only displays the "irqaction mask" in the "irq" command if the member is present. It fixes the following error (kernel was 2.6.33): crash> irq irq: invalid structure member offset: irqaction_mask FILE: kernel.c LINE: 5001 FUNCTION: generic_dump_irq() [./crash.orig] error trace: 8097e44 => 8109541 => 810c0ec => 8156299 Signed-off-by: Bernhard Walle <bernhard(a)bwalle.de&gt;
