Subject: Re: [PATCH v2] Remove deprecated IRQF_DISABLED flag entirely
Date: Fri, 6 Mar 2015 10:31:38 -0800 [thread overview]
Message-ID: <20150306183137.GZ13520@atomide.com> (raw)
In-Reply-To: <1425565425-12604-1-git-send-email-valentinrothberg@gmail.com>
* Valentin Rothberg <valentinrothberg@gmail.com> [150305 06:24]:
> The IRQF_DISABLED is a NOOP and has been scheduled for removal since
> Linux v2.6.36 by commit 6932bf37bed4 ("genirq: Remove IRQF_DISABLED from
> core code").
>
> According to commit e58aa3d2d0cc ("genirq: Run irq handlers with
> interrupts disabled") running IRQ handlers with interrupts enabled can
> cause stack overflows when the interrupt line of the issuing device is
> still active.
>
> This patch ends the grace period for IRQF_DISABLED (i.e., SA_INTERRUPT
> in older versions of Linux) and removes the definition and all remaining
> usages of this flag.
