12 /* The difference between SOCKBUF_AVAIL and SOCKBUF_DELETED is that DELETED
13 means it's invalid but not available for use yet. That happens when you
14 delete a sockbuf from within sockbuf_update_all(). Otherwise, when you
15 create a new sockbuf after you delete one, you could get the same idx,
16 and sockbuf_update_all() might trigger invalid events for it. */
