Subject: mm/sl[aou]b: Move common kmem_cache_size() to slab.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=242860a47a75b933a79a30f6a40bf4858f4a3ecc;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

mm/sl[aou]b: Move common kmem_cache_size() to slab.h

This function is identically defined in all three allocators
and it's trivial to move it to slab.h

Since now it's static, inline, header-defined function
this patch also drops the EXPORT_SYMBOL tag.
