| 2016-08-22 | genirq/affinity: Use get/put_online_cpus around cpumask operations | Christoph Hellwig | |
| Without locking out CPU mask operations we might end up with an inconsistent view of the cpumask in the function. Fixes: 5e385a6ef31f: "genirq: Add a helper to spread an affinity mask for MSI/MSI-X vectors" Signed-off-by: Christoph Hellwig <hch@lst.de> Link: http://lkml.kernel.org/r/1470924405-25728-1-git-send-email-hch@lst.de Signed-off-by: Thomas Gleixner <tglx@linutronix.de> | |||
| 2016-07-04 | genirq: Add a helper to spread an affinity mask for MSI/MSI-X vectors | Christoph Hellwig | |
| This is lifted from the blk-mq code and adopted to use the affinity mask concept just introduced in the irq handling code. It tries to keep the algorithm the same as the one current used by blk-mq, but improvements like assining vectors on a per-node basis instead of just per sibling are possible with this simple move and refactoring.
