. In this case, we want all RDMA READ requests to be served by
the address space of the migration process directly (not by CRIU). This
patchset implements a new uverbs command which allows an application to
register a memory region in the address space of another process.

A small patchset to update the verbs API documentation with some
information regarding the ioctl syscall. First patch converts the
file format to ReST, since this is the new preferred format, moves
the file to Documentation/userspace-api, and updates the index.
The 2nd patch adds the new content,
this documents a userspace API, its home should be with the
other userspace API docs.
This is in preparation for updating the content in a subsequent
patch.

Link the previously converted Documentation/infiniband/user_verbs.rst

root document. This manifests as a new section under "Kernel API
Documentation" in the index.html, as well as a new section in the
