--- Comment #1 from Jordan Gordeev <[email protected]> ---
This use-after-free is related to keeping a file residing on a UFS filesystem
open after that filesystem is unmounted. The concept of mounting and unmounting
filesystems was introduced in the loader by Toomas Soome. He is also the person
who introduced vdisks support in the loader. I'm adding him to the CC list so
he can help come up with an idea on how to make these two features work
together.
