    slub: use size and objsize orders to disable debug flags · 3de47213
    David Rientjes authored
    This patch moves the masking of debugging flags which increase a cache's
    min order due to metadata when `slub_debug=O' is used from
    kmem_cache_flags() to kmem_cache_open().
    Instead of defining the maximum metadata size increase in a preprocessor
    macro, this approach uses the cache's ->size and ->objsize members to
    determine if the min order increased due to debugging options.  If so,
    the flags specified in the more appropriately named DEBUG_METADATA_FLAGS
    are masked off.
    This approach was suggested by Christoph Lameter
