[PATCH] rxrpc: Use pr_<level> and pr_fmt, reduce object size a few KB
Joe Perches
joe at perches.com
Thu Jun 2 12:08:52 PDT 2016
Use the more common kernel logging style and reduce object size.
The logging message prefix changes from a mixture of
"RxRPC:" and "RXRPC:" to "af_rxrpc: ".
$ size net/rxrpc/built-in.o*
text data bss dec hex filename
64172 1972 8304 74448 122d0 net/rxrpc/built-in.o.new
67512 1972 8304 77788 12fdc net/rxrpc/built-in.o.old
Miscellanea:
o Consolidate the ASSERT macros to use a single pr_err call with
decimal and hexadecimal output and a stringified #OP argument
