From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Hi, >From Yishai, ----------------------------------------------------------------------- This series enables using indirect mkey over DEVX. The first patch recognizes the creation of an indirect mkey as part of DEVX object creation, in that case the umem valid bit shouldn't be set as this mkey doesn't really hold a umem. The next two patches manage indirection mkey upon DEVX flow to support ODP. To support a page fault event on an indirection mkey it needs to be part of the device mkey radix tree. Both the creation and the deletion flows for a DEVX object which is indirection mkey were adapted to handle that. In addition, the page fault flow was adapted to support indirect mkey type, it's handled in a similar flow as of the memory window mkey type.
