There have been a number of reports of people seeing the message: "name_count maxed, losing inode data: dev=00:05, inode=3185" in dmesg. These usually lead to people reporting problems to the filesystem group who are in turn clueless what they mean. Eventually someone finds me and I explain what is going on and that these come from the audit system. The basics of the problem is that the audit subsystem never expects a single syscall to 'interact' (for some wish washy meaning of interact) with more than 20 inodes. But in fact some operations like loading kernel modules can cause changes to lots of inodes in debugfs. There are a couple real fixes being bandied about including removing the fixed compile time limit of 20 or not auditing changes in debugfs (or both) but neither are small and obvious so I am not sending them for immediate inclusion (I hope Al forwards a real solution next devel window). In the meantime this patch simply adds 'audit' to the beginning ...
