Webto use the "list -H" option. For example, each of the kernel's pid_hash[] chains is headed by an hlist_head structure, which links a chain of "upid" structures: crash> whatis pid_hash struct hlist_head *pid_hash; crash> upid struct upid { int nr; struct pid_namespace *ns; struct hlist_node pid_chain; } SIZE: 32 WebAvoiding extra smp_rmb()¶ With hlist_nulls we can avoid extra smp_rmb() in lockless_lookup() and extra smp_wmb() in insert function. For example, if we choose to store the slot number as the ‘nulls’ end-of-list marker for each slot of the hash table, we can detect a race (some writer did a delete and/or a move of an object to another chain) …
