The branch main has been updated by des: URL: https://cgit.FreeBSD.org/src/commit/?id=4ebcdb8dd9a7bdddbc97ff6ee47e0a7556c76b5a commit 4ebcdb8dd9a7bdddbc97ff6ee47e0a7556c76b5a Author: Dag-Erling Smørgrav <des@FreeBSD.org> AuthorDate: 2026-08-05 08:50:47 +0000 Commit: Dag-Erling Smørgrav <des@FreeBSD.org> CommitDate: 2026-08-05 08:50:47 +0000 pseudofs: Don't purge the cache on shutdown This is a waste of time and results in a use-after-free if linsysfs is loaded and a USB network interface is in use, since USB devices are disconnected at shutdown, which triggers a call into linsysfs, which then tries to destroy a pseudofs node which has already been purged.
