 29  * SLAB_DESTROY_BY_RCU - **WARNING** READ THIS!
 30  *
 31  * This delays freeing the SLAB page by a grace period, it does _NOT_
 32  * delay object freeing. This means that if you do kmem_cache_free()
 33  * that memory location is free to be reused at any time. Thus it may
 34  * be possible to see another object there in the same RCU grace period.
 35  *
 36  * This feature only ensures the memory location backing the object
 37  * stays valid, the trick to using this is relying on an independent
 38  * object validation pass. Something like:
 39  *
 40  *  rcu_read_lock()
 41  * again:
 42  *  obj = lockless_lookup(key);
 43  *  if (obj) {
 44  *    if (!try_get_ref(obj)) // might fail for free objects
 45  *      goto again;

 48  *      put_ref(obj);

390  * %__GFP_COLD - Request cache-cold pages instead of
391  *   trying to return cache-warm pages.
392  *
393  * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
394  *
395  * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
396  *   (think twice before using).
397  *
398  * %__GFP_NORETRY - If memory is not immediately available,
399  *   then give up at once.
400  *
401  * %__GFP_NOWARN - If allocation fails, don't issue any warnings.
402  *
403  * %__GFP_REPEAT - If allocation fails initially, try once more before failing.
404  *
405  * There are other flags available as well, but these are not intended
406  * for general use, and so are not documented here. For a full list of
407  * potential flags, always refer to linux/gfp.h.
