kmem_cache_t * kmem_cache_create (const char * name, size_t size, size_t offset, unsigned long flags, void (*ctor) void*, kmem_cache_t *, unsigned long, void (*dtor) void*, kmem_cache_t *, unsigned long);
Returns a ptr to the cache on success, NULL on failure. Cannot be called within a int, but can be interrupted. The ctor is run when new pages are allocated by the cache and the dtor is run before the pages are handed back.
name must be valid until the cache is destroyed. This implies that the module calling this has to destroy the cache before getting unloaded.
The flags are
SLAB_POISON - Poison the slab with a known test pattern (a5a5a5a5) to catch references to uninitialised memory.
SLAB_RED_ZONE - Insert `Red' zones around the allocated memory to check for buffer overruns.
SLAB_NO_REAP - Don't automatically reap this cache when we're under memory pressure.
SLAB_HWCACHE_ALIGN - Align the objects in this cache to a hardware cacheline. This can be beneficial if you're counting cycles as closely as davem.
