 The first field we will discuss is `gfp_mask`:
 
-Low-level kernel memory allocation functions take a set of flags as - `gfp_mask`, which describes how that allocation is to be performed. These `GFP_` flags which control the allocation process can have following values: (`GF_NOIO` flag) means sleep and wait for memory, (`__GFP_HIGHMEM` flag) means high memory can be used, (`GFP_ATOMIC` flag) means the allocation process has high-priority and can't sleep etc.

 * `GFP_NOIO` - can sleep and wait for memory;
 * `__GFP_HIGHMEM` - high memory can be used;
