Is this really safe?


What's unsafe about it?  rpc_peeraddr2str() is designed to be called 
this way.

[PATCH 05/25] NFS: eliminate NIPQUAD(clp->cl_addr.sin_addr)

2007-11-13 Thread Chuck Lever
To ensure the NFS client displays IPv6 addresses properly, replace
address-specific NIPQUAD() invocations with a call to the RPC client to
get a formatted string representing the remote peer's address.
