Hi Dave,
The patch a8739514fa91: "list_lru: per-node list infrastructure" in -mm
has a signedness bug.
include/linux/list_lru.h
116 static inline unsigned long
117 list_lru_walk(struct list_lru *lru, list_lru_walk_cb isolate,
118 void *cb_arg, unsigned long nr_to_walk)
119 {
120 long isolated = 0;
121 int nid;
122
123 for_each_node_mask(nid, lru->active_nodes) {
124 isolated += list_lru_walk_node(lru, nid, isolate,
125 cb_arg, &nr_to_walk);
126 if (nr_to_walk <= 0)
^^^^^^^^^^^^^^^
nr_to_walk is unsigned so the timeout value from list_lru_walk_node() is
ULONG_MAX (it's not zero).
127 break;
128 }
129 return isolated;
130 }
regards,
dan carpenter
