Subject: sysctl extern cleanup: rcu
X-Git-Tag: v2.6.34-rc2~73
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e5ab67726f33b50f40db0ccf271ceb3c658554d5;p=platform%2Fkernel%2Flinux-stable.git

sysctl extern cleanup: rcu

Extern declarations in sysctl.c should be moved to their own header file,
and then include them in relavant .c files.

Move rcutorture_runnable extern declaration to linux/rcupdate.h
