kmem_cache_create - Create a cache.
kmem_cache_t * kmem_cache_create (const char * name, size_t size,
size_t align, unsigned long flags,
void (*ctor) <funcparams>void*, kmem_cache_t *, unsigned long</funcparams>,
void (*dtor) <funcparams>void*, kmem_cache_t *, unsigned long</funcparams>);
name A string which is used in /proc/slabinfo to identify this cache.
size The size of objects to be created in this cache.
align The required alignment for the objects.
flags SLAB flags
ctor A constructor for the objects.
dtor A destructor for the objects.
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
SLAB_HWCACHE_ALIGN - Align the objects in this cache to a hardware
cacheline. This can be beneficial if you’re counting cycles as closely
