https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255208 --- Comment #7 from Guido Falsi <madpilot@FreeBSD.org> --- Created attachment 224342 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D224342&action= =3Dedit vboxvfs patch Please disregard my comment #6 I think I found the problem, I'm attaching an untested patch. I'm going to = test it tomorrow myself. I'm reasonably sure problem is caused by base commit 6fa079fc3f5e (svn r355= 790) [1] There a VFS_VOP_VECTOR_REGISTER() call is performed on the vnodeops struct.= I'm not sure what it does, but it missing could explain why a null function poi= nter ends up being called. If anyone wants to test, and report back they are welcome, but please note = that I have not even tried compiling it for now.
