From 9beb266f2d7e5362c5bb9f999255aa1af5318aef Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 11 Sep 2013 14:24:40 -0700 Subject: [PATCH] exec: proc_exec_connector() should be called only once A separate one-liner with the minor fix. PROC_EVENT_EXEC reports the "exec" event, but this message is sent at least twice if search_binary_handler() is called by ->load_binary() recursively, say, load_script(). Move it to exec_binprm(), this is "depth == 0" code too.
