The patch titled
Subject: slub: tidy up initialization ordering
has been removed from the -mm tree. Its filename was
slub-make-sure-struct-kmem_cache_node-is-initialized-before-publication.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alexander Potapenko <glider@xxxxxxxxxx>
Subject: slub: tidy up initialization ordering
- free_kmem_cache_nodes() frees the cache node before nulling out a
reference to it
- init_kmem_cache_nodes() publishes the cache node before initializing it
Neither of these matter at runtime because the cache nodes cannot be
looked up by any other thread. But it's neater and more consistent to
reorder these.
