From 5e43aef530ba39206f7923295388f7ec3c5a7d93 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 26 May 2010 14:43:07 -0700 Subject: [PATCH] coredump: factor out put_cred() calls Given that do_coredump() calls put_cred() on exit path, it is a bit ugly to do put_cred() + "goto fail" twice, just add the new "fail_creds" label.
