slub: Deal with config variable dependencies
count_partial() is used by both slabinfo and the sysfs proc support. Move the function directly before the beginning of the sysfs code so that it can be easily found. Rework the preprocessor conditional to take into account that slub sysfs support depends on CONFIG_SYSFS *and* CONFIG_SLUB_DEBUG. Make CONFIG_SLUB_STATS depend on CONFIG_SLUB_DEBUG and CONFIG_SYSFS. There is no point of keeping statistics if no one can restrive them. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
