[PATCH v2 0/7] SR-IOV fixes and cleanup

From: Bjorn Helgaas
Date: Thu Oct 29 2015 - 18:22:55 EST

This is basically a revision of Alex's recent series:

I squashed some fixes into the original patch, dropped two, and split
the rest up a little differently:

iov: Update virtfn_max_buses to validate offset and stride
Folded into the patch it fixed

iov: Reset resources to 0 if totalVFs increases after enabling ARI
Dropped on the theory that the resource allocation code
should already handle this case

iov: Fix sriov_enable exception handling path
Split into a couple patches to make it easier to review

iov: Variable and loop cleanup for sriov_disable and sriov_enable
Dropped for readability

iov: Update sriov_enable to correctly handle offset and stride
Split into the piece that removes code made redundant by "PCI: Set
SR-IOV NumVFs to zero after enumeration" and the piece that fixes
the bug (using offset/stride before setting numVFs)

This is all on my pci/virtualization branch, and I'm still hoping to
merge this for v4.4.


Alexander Duyck (7):
PCI: Set SR-IOV NumVFs to zero after enumeration
PCI: Remove redundant validation of SR-IOV offset/stride registers
PCI: Remove VFs in reverse order if virtfn_add() fails
PCI: Reorder pcibios_sriov_disable()
PCI: Wait 1 second between disabling VFs and clearing NumVFs
PCI: Fix sriov_enable() error path for pcibios_enable_sriov() failures
PCI: Set NumVFs before computing how many buses VFs require
