Well, not for these traces, no. The trace contains __slab_alloc() in the 
call chain, which definitely fingers SLUB, not slab, despite the name 
(slab calls its allocation routines "cache_alloc", while slub calls them 
"slab_alloc" ;)

So the patch looks fine, and I applied it, but as Mel already mentioned, 
it looks like it won't be making any difference for Alexander.
