Subject[PATCH v2 0/5] PCI: Endpoint: Miscellaneous improvements
Date
Changes from v1:
Rebased to Linux 5.6-rc1 and removed dependencies to my other series
to unblock [1]

[1] -> http://lore.kernel.org/r/20200103100736.27627-1-vidyas@nvidia.com

v1 of this patch series can be found @
http://lore.kernel.org/r/20191231100331.6316-1-kishon@ti.com

This series adds miscellaneous improvements to PCIe endpoint core.
1) Protect concurrent access to memory allocation in pci-epc-mem
2) Replace spinlock with mutex in pci-epc-core and also use
notification chain mechanism to notify EPC events to EPF driver.
3) Since endpoint function device can be created by multiple
mechanisms (configfs, devicetree, etc..), allowing each of these
mechanisms to assign a function number would result in mutliple
endpoint function devices having the same function number. In order
to avoid this, let EPC core assign a function number to the
endpoint device.

Kishon Vijay Abraham I (5):
PCI: endpoint: Use notification chain mechanism to notify EPC events
to EPF
PCI: endpoint: Replace spinlock with mutex
PCI: endpoint: Protect concurrent access to memory allocation with
mutex
PCI: endpoint: Protect concurrent access to pci_epf_ops with mutex
PCI: endpoint: Assign function number for each PF in EPC core
