Subject: count_partial() is not used if !SLUB_DEBUG and !CONFIG_SLABINFO
X-Git-Tag: v2.6.25-rc8~83^2~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=53625b4204753b904addd40ca96d9ba802e6977d;p=linux-2.6

count_partial() is not used if !SLUB_DEBUG and !CONFIG_SLABINFO

Avoid warnings about unused functions if neither SLUB_DEBUG nor CONFIG_SLABINFO
is defined. This patch will be reversed when slab defrag is merged since slab
defrag requires count_partial() to determine the fragmentation status of
slab caches.
