Subject: [patch -mm 3/4] mempolicy: small header file cleanup
Date: Thu, 6 Mar 2008 12:05:06 -0800 (PST)	[thread overview]
Message-ID: <alpine.DEB.1.00.0803061136160.18590@chino.kir.corp.google.com> (raw)
In-Reply-To: <alpine.DEB.1.00.0803061135560.18590@chino.kir.corp.google.com>

Removes forward definition of vm_area_struct in linux/mempolicy.h.  We
already get it from the linux/slab.h -> linux/gfp.h include.

Removes the unused mpol_set_vma_default() macro from linux/mempolicy.h.

Removes the extern definition of default_policy since it is only
referenced, as it should be, in mm/mempolicy.c.
