This is the final update to the series with a few corner cases fixes vs. V5 which can be found here: https://lkml.kernel.org/r/20190214204755.819014197@linutronix.de The series applies against: git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git master and is also available from: git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.irq Changes vs. V5: - Change the invocation for the driver callback so it is invoked even when there are no interrupts left to spread out. That ensures that the driver can adjust to the situation (in case of NVME a single interrupt) - Make sure the callback is invoked in the legacy irq fallback case so the driver is not in a stale state from a failed MSI[X} allocation attempt. - Fix the adjustment logic in the NVME driver as pointed out by Ming and Marc, plus another corner case I found during testing. - Simplify the unmanaged set support Thanks, tglx 8<------------- drivers/nvme/host/pci.c | 117 +++++++++++++--------------------------- drivers/pci/msi.c | 39 +++++-------- drivers/scsi/be2iscsi/be_main.c | 2 include/linux/interrupt.h | 35 ++++++++--- include/linux/pci.h | 4 - kernel/irq/affinity.c | 116 ++++++++++++++++++++++++--------------- 6 files changed, 153 insertions(+), 160 deletions(-)
