Specialized structures in the animal's claws can seemingly absorb impact.
"Since 2002 (change "Replace BKL for chain locking with sysvfs-private rwlock") the sysv filesystem was doing IO under a rwlock in its get_block() function (yes, a non-sleepable lock hold over a function used to read inode metadata for all reads and writes). Nobody noticed until syzbot in 2023. This shows nobody is using the filesystem. Just drop it."
pkg-stage.sh: Remove kde entirely
The package set for FreeBSD 13.5 comes from the 2025Q1 branch, which doesn't have the new x11/kde (aka KDE 6) port; but shipping x11/kde5 (which is still in the 2025Q1 branch) doesn't make much sense either since a few weeks after the release that will no longer be available in either "latest" or "quarterly" package sets.
Just remove KDE packages from the 13.5 DVD entirely; this also makes the DVD image fit into 4.7 GB size limit of physical DVDs again.
