From 69292a8e40f4dae8af5f04724e06392cdf03c09e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Tue, 23 Aug 2022 20:20:04 +0200 Subject: util: accept iova_tree_remove_parameter by value MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It's convenient to call iova_tree_remove from a map returned from iova_tree_find or iova_tree_find_iova. With the current code this is not possible, since we will free it, and then we will try to search for it again. Fix it making accepting the map by value, forcing a copy of the argument. Not applying a fixes tag, since there is no use like that at the moment.
