Type:struct stable_node

Parameter:

TypeParameterName
struct stable_node *dup
struct rb_root *root
593  chain = alloc_stable_node()
594  VM_BUG_ON(is_stable_node_chain(dup))
595  If Value is more likely to compile time(chain) Then
596  INIT_HLIST_HEAD( & hlist)
597  chain_prune_time = jiffies
598  rmap_hlist_len = STABLE_NODE_CHAIN can be any negative number in* rmap_hlist_len negative range, but better not -1 to be able* to reliably detect underflows.

620  Return chain
Caller
NameDescribe
stable_tree_searchstable_tree_search - search for page inside the stable tree* This function checks if there is a page inside the stable tree* with identical content to the page that we are scanning right now
stable_tree_insertstable_tree_insert - insert stable tree node pointing to new ksm page* into the stable tree.* This function returns the stable tree node just allocated on success,* NULL otherwise.
