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/[email protected]
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
