/* Avoid kmemleak tracing */
#define SLAB_NOLEAKTRACE ((slab_flags_t __force)0x00800000U)
/*
* Prevent merging with compatible kmem caches. This flag should be used
* cautiously. Valid use cases:
*
* - caches created for self-tests (e.g. kunit)
* - general caches created and used by a subsystem, only when a
* (subsystem-specific) debug option is enabled
* - performance critical caches, should be very rare and consulted with slab
* maintainers, and not used together with CONFIG_SLUB_TINY
