[RFC][PATCH] (#5, U3) filesystem auditing

Hello, - This patch reorders the hooks to be consistently placed above the security hooks (Thanks Serge). - It also removes the audit_notify_watch() hooks from vfs_rmdir and vfs_unlink and places it in may_delete() (Thanks Stephen). - Stripped out the auditfs_enable feature because there was no outstanding use-case for it. We determined it was sufficient to have the compile time configure option only. (Thanks David, Thanks Steve). Sorry I didn't get this out sooner David. Also, what I'm doing with reference counting and locking doesn't seem to be too clear (and it really isn't) -- I apologize for that. Though this will all be described in detail in a document, I'll go ahead and send out an e-mail explaining what's going on. -tim -- -tim
