4.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Moshe Shemesh <moshe@xxxxxxxxxxxx> [ Upstream commit 461d5f1b59490ce0096dfda45e10038c122a7892 ] mlx4_delete_all_resources_for_slave in resource tracker should free all memory allocated for a slave. While releasing memory of fs_rule, it misses releasing memory of fs_rule->mirr_mbox.
