The patch titled
Transform kmem_cache_alloc()+memset(0) -> kmem_cache_zalloc().
has been removed from the -mm tree. Its filename was
transform-kmem_cache_allocmemset0-kmem_cache_zalloc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Transform kmem_cache_alloc()+memset(0) -> kmem_cache_zalloc().
From: "Robert P. J. Day" <rpjday@mindspring.com>
Replace appropriate pairs of "kmem_cache_alloc()" + "memset(0)" with the
corresponding "kmem_cache_zalloc()" call.
