Subject: [KJ] [PATCH] [RESEND] bonding - uninitialize static variables

One of the tasks at http://janitor.kernelnewbies.org/TODO
is described as
"
uninitialize static variables initialized to 0, to make it go to the
.bss, instead of .data.
"

To proof that it is still guaranteed that those variables will be
initialized to zero

Tom Bradley <tojabr@gmail.com> (on the kernel-janitors mailing list)
wrote
"
the default for gcc is `-fzero-initialized-in-bss', the kernel
makefile does not change this therefore bss is zeroed, this is
documented in the gcc manpage.
"

and David P Howell <david.p.howell@intel.com> added that
"
By definition .bss is always zero'ed by the implementation.
"

This patch uninitializes five static int initialized to 0.
