FREE_BOOTMEM_WITH_AC(9) 				    Memory Management in Linux					   FREE_BOOTMEM_WITH_AC(9)

NAME

       free_bootmem_with_active_regions - Call free_bootmem_node for each active range

SYNOPSIS

       void free_bootmem_with_active_regions(int nid, unsigned long max_low_pfn);

ARGUMENTS

       nid
	   The node to free memory on. If MAX_NUMNODES, all nodes are freed.

       max_low_pfn
	   The highest PFN that will be passed to free_bootmem_node

DESCRIPTION

       If an architecture guarantees that all ranges registered with add_active_ranges contain no holes and may be freed, this this function may
       be used instead of calling free_bootmem manually.

KMEM_CACHE_CREATE(9)                                        Memory Management in Linux                                        KMEM_CACHE_CREATE(9)

NAME

       kmem_cache_create - Create a cache.

SYNOPSIS

       struct kmem_cache * kmem_cache_create(const char * name, size_t size, size_t align, unsigned long flags, void (*ctor) (void *));

ARGUMENTS

       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.

DESCRIPTION

       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.

       name must be valid until the cache is destroyed. This implies that the module calling this has to destroy the cache before getting
       unloaded. Note that kmem_cache_name is not guaranteed to return the same pointer, therefore applications must manage it themselves.

       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_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.
