There issues were subtle and hard to detect especially without instrumenting the code during pci hotplug to look for them. Memory leaks, use after free, and needing pci hotplug to reproduce them made the kinds of bugs I saw when I was working with it easy to go unnoticed in light testing. Beyond that the code has the deep issue that the code breaks normal filesystem expectations in a way that is certain to confuse filesystem people like Al Viro. And yes that code being at all recursive is one of the things that Viro objected to when you had him review sysfs before merging my cleanups long ago. Recursive removal is absolutely unnecessary, and it hides bugs, and makes the code unnecessarily complex for no good reason.
