Subject: sysctl extern cleanup: C_A_D
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=eb5572fed55f4c2b7dbc42582bc82dcb47632380;p=deliverable%2Flinux.git

sysctl extern cleanup: C_A_D

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

Move C_A_D extern variable declaration to linux/reboot.h
