The patch titled
Subject: slab: make kmalloc_size() return "unsigned int"
has been removed from the -mm tree. Its filename was
slab-make-kmalloc_size-return-unsigned-int.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alexey Dobriyan <adobriyan@xxxxxxxxx>
Subject: slab: make kmalloc_size() return "unsigned int"
kmalloc_size() derives size of kmalloc cache from internal index,
which can't be negative.
Propagate unsignedness a bit.
