[PATCH v2 11/20] xprtrdma: Re-organize the switch() in rpcrdma_conn_upcall

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

 



Clean up: Eliminate the FALLTHROUGH into the default arm to make the
switch easier to understand.

Also, as long as I'm here, do not display the memory address of the
target rpcrdma_ep. A hashed memory address is of marginal use here.
