[PATCH net-next 14/14] net/smc: remove obsolete link state DELETING

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The connection layer in af_smc.c is now using the new LLC flow
framework, which made the link state DELETING obsolete. Remove the state
and the respective helpers.
