[PATCH] RDMA: Split kernel-only global device caps from uvers device caps

Jason Gunthorpe jgg at nvidia.com
Mon Apr 4 09:18:00 PDT 2022


Split ib_device::device_cap_flags into kernel_cap_flags that holds the
flags only used by the kernel.

This cleanly splits out the uverbs flags from the kernel flags to avoid
confusion in the flags bitmap.
