Commit-ID: f3637a5f2e2eb391ff5757bc83fb5de8f9726464 Gitweb: http://git.kernel.org/tip/f3637a5f2e2eb391ff5757bc83fb5de8f9726464 Author: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> AuthorDate: Thu, 7 Jul 2011 22:32:17 +0200 Committer: Thomas Gleixner <tglx@xxxxxxxxxxxxx> CommitDate: Thu, 28 Jul 2011 11:23:21 +0200 irq: Always set IRQF_ONESHOT if no primary handler is specified If no primary handler is specified then a default one is assigned which always returns IRQ_WAKE_THREAD. This handler requires the IRQF_ONESHOT flag on LEVEL / EIO typed irqs because the source of interrupt is not disabled. Since it is required for those users and there is no difference for others it makes sense to add this flag unconditionally.
