[IPV4]: Do not disable preemption in trie_leaf_remove().
Hello, Just discussed this Patrick... We have two users of trie_leaf_remove, fn_trie_flush and fn_trie_delete both are holding RTNL. So there shouldn't be need for this preempt stuff. This is assumed to a leftover from an older RCU-take. > Mhh .. I think I just remembered something - me incorrectly suggesting > to add it there while we were talking about this at OLS :) IIRC the > idea was to make sure tnode_free (which at that time didn't use > call_rcu) wouldn't free memory while still in use in a rcu read-side > critical section. It should have been synchronize_rcu of course, > but with tnode_free using call_rcu it seems to be completely > unnecessary. So I guess we can simply remove it.
