+/**
+ * kmalloc - allocate memory
+ * @size: how many bytes of memory are required.
+ * @flags: the type of memory to allocate.
+ *
+ * kmalloc is the normal method of allocating memory
+ * in the kernel.
+ *
+ * The @flags argument may be one of:
+ *
+ * %GFP_USER - Allocate memory on behalf of user. May sleep.
+ *
+ * %GFP_KERNEL - Allocate normal kernel ram. May sleep.
+ *
+ * %GFP_ATOMIC - Allocation will not sleep.
+ * For example, use this inside interrupt handlers.
+ *
+ * %GFP_HIGHUSER - Allocate pages from high memory.
+ *
+ * %GFP_NOIO - Do not do any I/O at all while trying to get memory.
+ *
+ * %GFP_NOFS - Do not make any fs calls while trying to get memory.
+ *
+ * Also it is possible to set different flags by OR'ing
+ * in one or more of the following additional @flags:
+ *
+ * %__GFP_COLD - Request cache-cold pages instead of
+ * trying to return cache-warm pages.
+ *
+ * %__GFP_DMA - Request memory from the DMA-capable zone.
+ *
+ * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
+ *
+ * %__GFP_HIGHMEM - Allocated memory may be from highmem.
+ *
+ * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
+ * (think twice before using).
+ *
+ * %__GFP_NORETRY - If memory is not immediately available,
+ * then give up at once.
+ *
+ * %__GFP_NOWARN - If allocation fails, don't issue any warnings.
+ *
+ * %__GFP_REPEAT - If allocation fails initially, try once more before failing.
