From d93e4c940f51ae06b59c14523c4d55947f9597d6 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Mon, 11 May 2009 20:47:15 -0400 Subject: [PATCH] securityfs: securityfs_remove should handle IS_ERR pointers Both of the securityfs users (TPM and IMA) can call securityfs_remove and pass an IS_ERR(dentry) in their failure paths. This patch handles those rather than panicing when it tries to start deferencing some negative memory.
