James Smart ea96d6496f nvmet_fc: support target port removal with nvmet layer ... Currently, if a targetport has been connected to via the nvmet config (in other words, the add_port() transport routine called, and the nvmet port pointer stored for using in upcalls on new io), and if the targetport is then removed (say the lldd driver decides to unload or fully reset its hardware) and then re-added (the lldd driver reloads or reinits its hardware), the port pointer has been lost so there's no way to continue to post commands up to nvmet via the transport port. Correct by allocating a small "port context" structure that will be linked to by the targetport. The context will save the targetport WWN's and the nvmet port pointer to use for it. Initial allocation will occur when the targetport is bound to via add_port. The context will be deallocated when remove_port() is called. If a targetport is removed while nvmet has the active port context, the targetport will be unlinked from the port context before removal. If a new targetport is registered, the port contexts without a binding are looked through and if the WWN's match (so it's the same as nvmet's port context) the port context is linked to the new target port. Thus new io can be received on the new targetport and operation resumes with nvmet. Additionally, this also resolves nvmet configuration changing out from underneath of the nvme-fc target port (for example: a nvmetcli clear).
