   * kmalloc is the normal method of allocating memory
   * for objects smaller than page size in the kernel.

-  * %GFP_KERNEL - Allocate normal kernel ram.  May sleep.
+  * Below is a brief outline of the most useful GFP flags

-  * %GFP_ATOMIC - Allocation will not sleep.  May use emergency pools.
-  *   For example, use this inside interrupt handlers.
+  * %GFP_KERNEL

-  * %GFP_HIGHUSER - Allocate pages from high memory.

+  *    Allocation will not sleep.

-  * %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.

-  * %GFP_NOWAIT - Allocation will not sleep.
-  *
-  * %__GFP_THISNODE - Allocate node-local memory only.
-  *
-  * %GFP_DMA - Allocation suitable for DMA.
-  *   Should only be used for kmalloc() caches. Otherwise, use a

+  * %GFP_HIGHUSER
+  *    Allocate memory from high memory on behalf of user.

   * Also it is possible to set different flags by OR'ing
   * in one or more of the following additional @flags:
