You're probably familiar with this dreaded scenario when you first started out using Linux: accidentally removing an important file with the rm command. And of course, there's no recycling bin! In this talk I'll share with you one of my first kernel hacks - implementing an undo rm "unrm" operation in the Linux kernel. This talk aims to be a gentle introduction to kernel development, in the form of a project show-and-tell. We'll start our trace of a typical unrm call from userspace and make our way down to Linux's VFS layer. In the process, I'll show you what a typical kernel debugging session might look like, and how you might make changes and run your kernel. In the end we'll put these concepts together and demo unrm's functionality.


Jessica Yu

Jessica is a new computer science graduate and a fledgling Linux kernel developer. She enjoys exploring open source technologies, hacking on small projects, and contributing to the Linux community. This summer she will be joining Red Hat to continue pursuing these interests.
