| From | Arnd Bergmann <> | Subject | [PATCH 15/19] sunrpc: don't warn for unused variable 'buf' | Date | Fri, 25 Jan 2013 14:14:32 +0000 |
| |
When RPC_DEBUG is unset, the dprintk() macro does nothing, causing the 'buf' variable in svc_printk to become unused. Marking it as __maybe_unused avoids a harmless gcc warning.
Without this patch, building at91_dt_defconfig results in:
net/sunrpc/svc.c: In function 'svc_printk': net/sunrpc/svc.c:1051:7: warning: unused variable 'buf' [-Wunused-variable]
