Detailed Description

An outgoing request is created on behalf of some incoming request to track the state of credit transfer with some remote domain.

An outgoing request is created to:

  • borrow a new credit from some remote owner (an "upward" request) or
  • revoke a credit sublet to some remote owner (a "downward" request) or
  • cancel this owner's credit and return it to an upward owner.

Before a new outgoing request is created, a list of already existing outgoing requests (m0_rm_owner::ro_outgoing) is scanned. If an outgoing request of a matching type for a greater or equal credit exists, new request is not created. Instead, the incoming request pins existing outgoing request.

m0_rm_outgoing fields and state transitions are protected by the owner's mutex.
