4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann arnd@arndb.de
commit f6ca9f46f6615c3a87529550058d1b468c0cad89 upstream.
The proc_create() and remove_proc_entry() functions do not reference their arguments when CONFIG_PROC_FS is disabled, so we get a couple of warnings about unused variables in IPVS:
ipvs/ip_vs_app.c:608:14: warning: unused variable 'net' [-Wunused-variable] ipvs/ip_vs_ctl.c:3950:14: warning: unused variable 'net' [-Wunused-variable] ipvs/ip_vs_ctl.c:3994:14: warning: unused variable 'net' [-Wunused-variable]
This removes the local variables and instead looks them up separately for each use, which obviously avoids the warning.
