Add sysctl KERN_LOCKF
reporting the shapshot of the active advisory locks.
A new VFS ops method vfs_report_lockf if provided in the mount point
op table. If it is NULL, as it is currently for all existing
filesystems, vfs_report_lockf() function is used, which gathers
information from the standard implementation inside kern/kern_lockf.c.
Filesystems implementing its own locking (NFSv4 as example) can provide
a custom implementation.

Nice! This is one of the things lsof has still groveled around in /dev/mem
directly for in the past. Hopefully the lsof developer will make use of this.
