The patch titled
Remove uses of kmem_cache_t from mm/* and include/linux/slab.h
has been added to the -mm tree. Its filename is
remove-uses-of-kmem_cache_t-from-mm-and-include-linux-slabh.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: Remove uses of kmem_cache_t from mm/* and include/linux/slab.h
From: Christoph Lameter <clameter@xxxxxxx>
Remove all uses of kmem_cache_t (the most were left in slab.h). The
typedef for kmem_cache_t is then only necessary for other kernel
subsystems. Add a comment to that effect.
