[RFC 6/7] Use an external declaration in exit.c for fs_cachep

From: Christoph Lameter
Date: Sat Nov 18 2006 - 00:46:28 EST


Use an external declaration in exit.c for fs_cachep.

fs_cachep is only used in kernel/exit.c and in kernel/fork.c.
It is defined in kernel/fork.c so we need to add an external
declaration to kernel/exit.c to be able to avoid the
declaration.
