Subject: [PATCH] Unit mismatch (Slab/SReclaimable/SUnreclaim) in meminfo

Hello, it seems there's mismatch in unit (byte and kB) in meminfo.
Would something like this will be acceptable?

commit d42f3245c7e2 ("mm: memcg: convert vmstat slab counters
to bytes") changed it to bytes but proc seems to print everything in
kilobytes.
