- * 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.
