title: Queues in the Linux Kernel
body: <p>I've been searching for information for a common kernel implementation of queues, that is, first-in-first-out data structures.  I thought there may be one since it's likely something that's common to use, and there's a standard for linked lists (in the form of the list_head structure).  Is there some standard queue implementation I can't find, or is it perhaps common practice to just use linked lists as queues and hope for the best?</p>
