[PATCH 7/7] lockd: Remove unused fields in the nlm_reboot structure

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

 



The nlm_reboot structure is used to store information provided by the
NSM_NOTIFY procedure.  This procedure is not specified by the NLM or NSM
protocols, other than to say that the procedure can be used to transmit
information private to a particular NLM/NSM implementation.

For Linux, the callback arguments include the name of the monitored host,
the new NSM state of the host, and a 16-byte private opaque.

As a clean up, remove the unused fields and the server-side XDR logic that
decodes them.
