  48. # are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since
  49. # there is no other way to identify defconfig builds, QTI internal
  50. # representation of perf builds (identified using the string 'perf'),
  51. # is used to identify if the build is a slub or defconfig one. This
  52. # way no critical debug feature will be enabled for perf and shipment
  53. # builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
  54. # config.
