From e8e66ed25b5cbeebed69c475f6c108e52078a3b3 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 28 Aug 2009 10:05:33 -0700 Subject: [PATCH] Do not call 'ima_path_check()' for each path component Not only is that a supremely timing-critical path, but it's hopefully some day going to be lockless for the common case, and ima can't do that. Plus the integrity code doesn't even care about non-regular files, so it was always a total waste of time and effort.
