+ *
+ * It is safe to use the allocator in NMI handlers and other special

+ *
+ * The lockless operation only works if there is enough memory
+ * available. If new memory is added to the pool a lock has to be
+ * still taken. So any user relying on locklessness has to ensure
+ * that sufficient memory is preallocated.
+ *
+ * The basic atomic operation of this allocator is cmpxchg on long.
+ * On architectures that don't have NMI-safe cmpxchg implementation,
+ * the allocator can NOT be used in NMI handler. So code uses the

+ * If there are multiple producers and multiple consumers, llist_add
+ * can be used in producers and llist_del_all can be used in
+ * consumers. They can work simultaneously without lock. But
+ * llist_del_first can not be used here. Because llist_del_first

+ *
+ * If there are multiple producers and one consumer, llist_add can be

+ *
+ * This can be summarized as follow:
+ *
+ * | add | del_first | del_all
+ * add | - | - | -
+ * del_first | | L | L
+ * del_all | | | -
+ *
+ * Where "-" stands for no lock is needed, while "L" stands for lock
+ * is needed.
+ *
+ * The list entries deleted via llist_del_all can be traversed with
+ * traversing function such as llist_for_each etc. But the list
+ * entries can not be traversed safely before deleted from the list.
+ * The order of deleted entries is from the newest to the oldest added
+ * one. If you want to traverse from the oldest to the newest, you
+ * must reverse the order by yourself before traversing.
+ *
+ * The basic atomic operation of this list is cmpxchg on long. On
