[patch -mm 3/4] mempolicy: small header file cleanup

David Rientjes
2008-03-06T20:06:16Z

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.
