This patchset is the second version of the patchset to add ESTALE handling to several syscalls. The previous version is here: http://lwn.net/Articles/496103/ I spoke with Al Viro about my previous set and he pointed out something I had not considered. getname() has side effects when auditing is enabled, so if we end up calling it multiple times for the same names, we'll make a mess of the audit handling. This patchset is a revised version that should fix that by ensuring that we only call getname() once per __user path, per syscall. In order to do that, I had to break up some of the nice user_path_* wrappers. I've tried to keep this patchset pretty granular. Some of these patches could be combined if that's desirable. It's probably too late for 3.5 here, but I'd like to see this considered for 3.6 if possible.
