Prev: [PATCH -mm 11/17] sysctl extern cleanup - module
Next: sysctl extern cleanup - binfmts
From: Dave Young on 21 Feb 2010 09:30
Extern declarations in sysctl.c should be move to their own head file,
and then include them in relavant .c files.

Move sysctl_nr_open_min, sysctl_nr_open_max extern declarations to linux/file.h
