Subject: count_partial() is not used if !SLUB_DEBUG and !CONFIG_SLABINFO
X-Git-Tag: MMI-PSA29.97-13-9~35854^2~1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53625b4204753b904addd40ca96d9ba802e6977d;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

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.
