Subject: mm/khugepaged: use KMEM_CACHE()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c14bdcc9f274620492aba7d920cc2641440cf1ba;p=users%2Fhch%2Fmisc.git

mm/khugepaged: use KMEM_CACHE()

We got some late review commits during review of commit b4c9ffb54b32
("mm/khugepaged: remove definition of struct khugepaged_mm_slot").  No
need to keep the old cache name "khugepaged_mm_slot", let's simply use
KMEM_CACHE().
